Just a note - building lib32-qt4 fails on my machine, someone on forum had similar experience, it's something about Webkit, didn't save exact error.

I could build 4.8.7-5 fine, but I just tried to build 4.8.7-6 and this failed. Here are the last few lines.

Looks like the problem is again with the same library and the fast fix didn't do the job...

Had the same build error as Moabit, solved by installing lib32-gstreamer0.10 0.10.36-5, lib32-gstreamer0.10-base 0.10.36-7 and lib32-gstreamer0.10-base-plugins 0.10.36-7 from AUR, strange that building something from official repo depends on libraries from AUR. Still getting segmentation fault.

I see additional messages/warnings in gdb compared to previous comments:

Since we don't ship skype anymore and nothing else depends on this (except for other lib32 stuff) I'd say drop it. It only seems to give trouble lately, and qt4 is EOL anyway.
