Application: dolphin (1.5) KDE Platform Version: 4.5.2 (KDE 4.5.2) Qt Version: 4.7.0 Operating System: Linux 2.6.35-22-generic x86_64 Distribution: Ubuntu 10.10 -- Information about the crash: - What I was doing when the application crashed: I don't really know how to trigger this bug but I manage to crash Dolphin three times while trying this setup. I had two Dolphin windows open. In one, I had selected two PDF files I just downloaded. In the other, I opened the folder I wanted to move the files to. While draggin the files I hovered the location bar and a popup with some subfolders at some level of the path was shown. I dropped the files there but selected "Cancel". Then started the dragging operation again and, when I reached the second windows Dolphin crashed. The crash can be reproduced some of the time. -- Backtrace: Application: Dolphin (dolphin), signal: Segmentation fault [Current thread is 1 (Thread 0x7fdb6a90d760 (LWP 12225))] Thread 2 (Thread 0x7fdb569e6710 (LWP 12230)): #0 0x00007fdb6a1ed1d3 in __poll (fds=<value optimized out>, nfds=<value optimized out>, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:87 #1 0x00007fdb61ddf009 in ??

yes. Definitely something to do with oxygen. Thanks Dario
mmm. Can't reproduce (after ~10 attempts at re-doing whats described in first comment)
I'm the original reporter. You're right, I can't get it to crash doing what I originally described. However, while trying to do that, Dolphin crashed twice but I'm not sure how or if it's due to the same bug. Here's the stack trace from this new crash. Is it there something else I could do to help you debug this problem?

This second crash is not related to oxygen. Its either Qt, Dolphin, or nepomuk. I'd suggest you create a different bug report with this one.
Ok. Then I guess the original bug is not valid anymore. At least, I can't reproduce it now (KDE SC 4.5.3). Thanks for your work!
... so closing.
