Bug Description

[ 2810.133252] pool[8519]: segfault at bc ip 00007f966bdabb71 sp 00007f962bfed040 error 4 in libpixman-1.so.0.32.4[7f966bd55000+a3000]

Compiz crashed and I saw the above line in the dmesg output.

Happens EVERY time I pressed "d" on the ubuntu button for file search (dash, icon on top in the sidebar).

Furthermore .xsession-errors has logged this as well:
upstart: unity7 main process (1925) killed by SEGV signal
upstart: unity7 main process ended, respawning

Pretty serious I'd say ...

dmesg on a debian system:

[ 8507.445846] dibosys-disp-40[21440]: segfault at 7f4a67fff000 ip 00007f4b01a4fa70 sp 00007fff57fdb098 error 4 in libpixman-1.so.0.33.6[7f4b019c1000+a0000]

..so the current libpixman version (0.33.6-1) seems to have the same problem, triggered using a gtk3 webkit browser written in perl (when running on xserver with 4k resolution, javascipt enabled and scrolling a web page 1 pixel at a time).. [reproducible, crash after scrolling about 50 pixels]

same effect (segfault) occurs with version 0.32.6-3

serious indeed, affects all our appliances / customers...
