From the backtrace, the crash seems to be Nepomuk-related -- Nepomuk was invoked when the rename dialog popped up and a preview of the files was shown. I'm reassigning it to the nepomuk product. I'm also CC'ing Peter Penz, as there are some KFileMetaDataWidget code that he might know about. I'm quite sure such kind of issues don't occur anymore as we use a custom process now to read the metadata (see http://ppenz.blogspot.com/2011/03/dont-crash-when-reading-metadata.html - KFileMetaDataWidget uses this approach on master). Usually deleting KFileMetaDataWidget while metadata is read should not crash also in KDE 4.6 but judging from the backtrace we have a case here... *** This bug has been marked as a duplicate of bug 280818 *** |
Application: ark (2.16) KDE Platform Version: 4.6.00 (4.6.0) "release 395" Qt Version: 4.7.2 Operating System: Linux 2.6.34.7-0.7-default i686 Distribution: "openSUSE 11.3 (i586)" -- Information about the crash: - What I was doing when the application crashed: Downloaded WordPress 3.1 to install into localhost. Extracted archive into /srv/www/htdocs/wordpress (permissions valid for this folder). Had closed existing WordPress install, but browser was still open (so Apache was likely running). Ark asked whether to overwrite existing files; I told it to overwrite all. A few seconds passed before Ark crashed. Did the extract a second time, with no issues. -- Backtrace: Application: Ark (ark), signal: Segmentation fault [Current thread is 1 (Thread 0xb4fb9710 (LWP 3147))] Thread 5 (Thread 0xb1e32b70 (LWP 3163)): #0 0xffffe430 in __kernel_vsyscall () #1 0xb5f285b3 in __lll_lock_wait_private () from /lib/libc.so.6 #2 0xb5ebb35f in _L_lock_10260 () from /lib/libc.so.6 #3 0xb5eb9ad6 in free () from /lib/libc.so.6 #4 0xb5616836 in g_free () from /usr/lib/libglib-2.0.so.0 #5 0xb560c523 in ??
