Hello,
in KDE we are getting a lot duplicate crash reports from users that run Archlinux. The original bug report is [1] and showed a crash when vlc is used as phonon backend. This was reported upstream in [2], but the VLC devs replied that this is a downstream problem. Indeed the bug has been fixed by most distributions (e.g. see [3]), but it seems Archlinux is still affected.
Antonio Rojas told me that Arch rebuilds the vlc plugin cache. I guess this is done by this hook [4] which is similar to what Debian does [5], but apparently there is something else that Arch is missing.

I would appreciate if we can use this ticket to track the status of this issue.

Thanks, Elvis. As I told you on IRC I'm not able to reproduce this and I have no clue how the vlc plugin cache is getting corrupted. So please refer upstream reporters to this ticket so they can provide the necessary info.

Users affected by this, please provide the output of the following commands:

pacman -Qo /usr/lib/vlc/plugins
pacman -Qkk vlc
stat -c "%Y %n" /usr/lib/vlc/plugins/*/* | sort
stat -c "%Y %n" /usr/lib/vlc/plugins/plugins.dat

and attach your /var/log/pacman.log file.

*AFTER* running these commands and posting the output, run the following command as root to fix your issue
/usr/lib/vlc/vlc-cache-gen -f /usr/lib/vlc/plugins

@Alif If you don't have vlc installed then your issue has nothing to do with this. If you can provide a backtrace, open a new issue.

Removing the comments to avoid unrelated noise.

@aichingm Thanks a lot. I was finally able to reproduce this and found out where the problem is.
Comment by Elvis Angelaccio (elvisangelaccio) - Tuesday, 24 January 2017, 18:48 GMT
@Antonio: we are still getting reports with this backtrace, for example https://bugs.kde.org/show_bug.cgi?id=375417

Can you have another look? Thanks!
Comment by Doug Newgard (Scimmia) - Tuesday, 24 January 2017, 18:49 GMT
Elvis, see if the user is using an old, unsupported freetype2 package (infinality being the main culprit).
Comment by Elvis Angelaccio (elvisangelaccio) - Sunday, 10 September 2017, 17:16 GMT
We are still getting quite a lot duplicate crash reports for this. What could be done to improve the situation? Maybe a news on archlinux.org recommending to remove infinality for Plasma users?
Comment by Eli Schwartz (eschwartz) - Sunday, 10 September 2017, 17:18 GMT
The question is the same question we had before. What is causing the crashes? Have you confirmed whether the users are using infinality or not?

And no, we don't need to make a news post to tell people not to use old, unsupported, broken software. Arch users are *supposed* to be capable enough to figure this out for themselves based on the software they explicitly installed. :(
Comment by Elvis Angelaccio (elvisangelaccio) - Sunday, 10 September 2017, 17:57 GMT
IIRC at least one user confirmed that removing infinality fixed his crashes. Another one mentioned some patched cairo package as the cause.
So there is nothing we can do? I just have the feeling that many users do not know they are using broken software.
Comment by Eli Schwartz (eschwartz) - Sunday, 10 September 2017, 18:17 GMT
No, not really. If it's just a matter of unsupported patched freetype, I think most Arch users who follow the forums etc. became aware due to the many threads about the issue back when infinality first became a problem. We've even more or less stopped getting people on IRC.
