[SOLVED] Every application segfaults on typing text

Hello,
Last night my browser (dwb) crashed while typing in URL after working properly for more than an hour.
After that I realised that EVERY graphical application will crash after typing in anything (eg. folder path in Spacefm, file name in Geany's Save As dialog, number in galculator), although VBox will crash after clicking on any menu.

Running any of these apps from terminal reveals segfault.

Here are few lines from dmesg:

[  478.803431] galculator[996]: segfault at 7fff38ac9ff8 ip 00007f50dda81090 sp 00007fff38aca008 error 6 in libc-2.15.so[7f50dda0b000+197000]
[   23.940121] spacefm[753]: segfault at 7fff57e0cff8 ip 00007fcd002a6090 sp 00007fff57e0d008 error 6 in libc-2.15.so[7fcd00230000+197000]
[  101.706968] geany[841]: segfault at 7fffb687cfc8 ip 00007f59752f017a sp 00007fffb687cfd0 error 6 in libc-2.15.so[7f5975287000+197000]
[ 2050.360604] VirtualBox[1317]: segfault at 7fffb3a94fd8 ip 00007f9ce0b9217a sp 00007fffb3a94fe0 error 6 in libc-2.15.so[7f9ce0b29000+197000]

I updated system yesterday in the morning, but I downgraded every package updated after the problem occured.
Few minutes ago I ran -Syu again because of glib-networking available for install and segfault related to glibc (which i reinstalled just to be sure), but nothing changed.
Any ideas?

Thanks in advance, Šaran.

This is most likely a hardware problem. Either graphic card, or RAM related.

Re: [SOLVED] Every application segfaults on typing text

Interesting that it always occurs at the same offset (197000)
Did you reboot?  (I hate that solution, it makes me feel like a Windows user)
What environment are you using? (Openbox, xfce4, etc.) 
Have you tried a different environment?

I rebooted more than a few times.
I'm using MonsterWM, just tried DWM, but it segfaults on launch.

[ 1845.030740] dwm[1195]: segfault at 7fff78588fc8 ip 00007fab280cc17a sp 00007fff78588fd0 error 6 in libc-2.15.so[7fab28063000+197000]

@kotnik, 4k video on youtube plays without issues and everything is fine in live Crunchbang.

Re: [SOLVED] Every application segfaults on typing text

I played with gdb and debugging showed some errors related to X11 cursor libraries, so I reinstalled xcursor-vanilla-dmz.
No more segfaults! Thanks for help.
