Bug reported failed with "unknown error" at the submit stage. Saved output below.
Application: dolphin (1.4)
KDE Platform Version: 4.4.00 (KDE 4.4.0)
Qt Version: 4.6.2
Operating System: Linux 2.6.32.9-67.fc12.x86_64 x86_64
Distribution (Platform): Fedora RPMs

-- Information about the crash:
Dolphin crashed when closing directory properties window - multiple properties windows open.

I had two Dolphin windows open on different external USB drives. I had opened the properties window on two "duplicate" directories (one on each drive) to confirm that the directory contents were identical. The directories were appoximately 220GiB in size with 94500 files in 1498 directories. I left the properties windows open for some time and ran multiple rsync operations between the two USB drives (none of which affected the directories for which the properties windows were open). I then closed the top properties window by selecting the cancel option and attempted to select the other Dolphin window. I am not clear if the crash happened as I selected the lower Dolphin window or following the selection of cancel in the first window (it happened very quickly in either case).

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