Hi,
out of the ca. 10 GUI programs I'm using regularly, only qtcreator and texmaker are affected.
They would crash right after start with a segmentation fault in do_lookup_x in ld-linux.so (so they don't even start).
Since I hadn't used these programs during the last week, I went down the downgrade road. When I first tried 2016/11/25, it was still broken.
After downgrading to the 2016/11/18 archive I found the programs working again. Pacman log between the two snapshots is as follows:
http://pastebin.com/Yx4FTQyt
Note that the output from 2016/11/24 was just an attempt to install pacaur, which I then did on the next day (end of log). Can the cause be switching from yaourt to pacaur? I can't imagine that.
Obviously I want to you up-to-date software again asap. What can I do? Determining the intersection of qtcreator dependencies, texmaker dependecies and packages upgraded, adding those to ignorePkg and doing the upgrade - or is there a better solution?
Thanks in advance.

Post the full backtrace, not just one line. Also, post the output of 'pacman -Qm'

As you can see from the backtrace, it's a Qt problem (came with the update from 5.7.0-3 to 5.7.0-6, I must have overlooked this). The backtrace is the same for both programs:

appmenu-qt5-bzr r40-1
And here is your problem. Remove it or rebuild it.

Thanks, rebuilding fixed the issue, but appmenu-qt5-bzr still doesn't work as it should. However, that's another story.
How could you find the cause so quickly? I spent some hours searching and debugging...
Thanks again!

Because you're not the first one to have this problem after those updates.
