Bug 176030

*** Bug 171552 has been marked as a duplicate of this bug. ***

I get the same(Or very similar) crash on my gentoo amd64 system with kde4.2 when opening dolphin. I also experience a crash anytime I do something that attempts to show a file selection dialog.
Backtrace for dolphin is below.

Application: Dolphin (dolphin), signal SIGSEGV
0x00007f71bfb75d81 in nanosleep () from /lib/libc.so.6

Deleting the .kde4 directory and letting it get regenerated seems to have fixed this for me somehow.

Same behaviour here: Dolphin crashs when I try to launch it

SVN commit 929837 by ervin:

Not sure how this situation happened, but can't hurt to check the access
pointer first to avoid such crashes in the future.
