Arch Linux

For instance, window decorations fail. And then, "dependency hell", trying to back-out the package.

testing/pango 1.42.0-1

To start, for instance:

$ /usr/bin/firefox-developer-edition
XPCOMGlueLoad error for file /usr/lib/firefox-developer-edition/libmozgtk.so:
/usr/lib/libpango-1.0.so.0: undefined symbol: g_log_structured_standard
Couldn\'t load XPCOM.

So, disable testing, and re-install pango, to extra/pango 1.40.14-2.

But then, for instance:

$ vim /etc/pacman.conf
vim: symbol lookup error: /usr/lib/libatk-1.0.so.0: undefined symbol: g_log_structured_standard

So, back-out testing/atk 2.28.0+2+g32f5756-1, to extra/atk 2.26.1-1.

But, for instance:

$ vim /etc/pacman.conf
vim: symbol lookup error: /usr/lib/libgdk-3.so.0: undefined symbol: g_log_structured_standard

So, back-out testing/gtk3 3.22.29+4+gb485cf91b5-1, to extra/gtk3 3.22.28-1.

This, at least, seems to make things usable again, even though there are other dependencies from testing.

Hmm - I suppose this symbol "g_log_structured_standard" is suppose to come from somewhere other than pango, and that all of the packages, pango, atk, and gtk3 are effected. Google says this symbol is from glib, in which case either this is a pango issue, or instead, is a glib issue.

For the moment, though, this version of pango - not by itself - makes the system unusable.
