Bug 234183

Application: dolphin (1.4)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.11-99.fc12.x86_64 x86_64
Distribution: "Fedora release 12 (Constantine)"

-- Information about the crash:
Tried to follow a symlink in /dev.  After canceling the window asking for which application to use, Dolphin crashed.  I think I clicked on an empty part of the window.

 -- Backtrace:
Application: Dolphin (dolphin), signal: Segmentation fault
87	  int result = INLINE_SYSCALL (poll, 3, CHECK_N (fds, nfds), nfds, timeout);
