[SOLVED] KDE sometimes dies while using Firefox

[chaoscommander]

Hey. Yesterday I applied the latest updates to X11 and now I face "random" crashes in which I find myself logged out of KDE without warning. This happens when I click certain links on certain websites or scroll with either my Synaptics Touchpad or with mouse wheel clicked (making that arrow-thingy appear, sorry for lack of proper vocabulary), but not when simply spinning the mouse wheel. Also, I can't consistently reproduce it, but if I can, it's always the same links or pages (such as the right-arrow on pr0gramm.com; NSFW, sorry ^^), but always just one dynamically-generated page, not all of them (in the example above, it only happens when switching over to one certain picture (an animated gif of a cat crawling into a bed), but not on others).
Deactivating JavaScript and Flash does not help. I have not installed, updated nor removed any plugins or extentions to Firefox and I have not up- or downgraded Firefox before this started happening.
Help? Might there be a bug in the latest X11 stuff?

I've had similar issues, much better since kernel 3.11.3+ using latest available mesa,xorg-server,libdrm and glamor with also changed my video card to a Radeon 7750 from a 4670.

More info here: https://bugs.freedesktop.org/show_bug.cgi?id=44099

Hope the info can give you some direction, I'm only familiar with respect to Radeon, not aware of it with other video cards.

I upgraded to kernel 3.10.7-r1 and it stopped happening.
