patch to guard against deref of NULL casefolded_exec ptr
Confirmed in fedora-16 too. Starting to search using system key crashes the shell. I got the same problem here after upgrading from Fedora-15 to Fedora-16. The following messages entries where created after hitting the first key in the activities view: Nov 23 17:51:55 bisonws0043 kernel: [27053.047119] gnome-shell[16207]: segfault at 0 ip 00007f5b4c83f028 sp 00007fff2883cd08 error 4 in libc-2.14.90.so[7f5b4c711000+1aa000] Nov 23 17:51:55 bisonws0043 gnome-session[16019]: WARNING: Application 'gnome-shell.desktop' killed by signal Using gnome-shell-3.2.1-2.fc16.x86_64 Using gnome-shell-3.2.1-2.fc16.x86_64 too, I got the same problem today after installing some Nautilus extensions ( nautilus-search-tool, nautilus-sendto, nautilus-pastebin ). I removed them and now no more crashes when I enter something in the search field. Maybe nothing to do. Indeed, removing nautilus-pastebin fixes the crashes for me as well. The other two plugins seem to not cause any trouble here. As soon as the pastebin-plugin is installed though, gnome-shell dies (and restarts) when i try to use the search functionality. I also found that removing nautilus-pastebin seems to have fixed the issue for me. Removing nautilus-pastebin fixed it for me too. Nautilus-pastebin has a desktop file that makes shell choke. there are other bugs similar to this: https://bugzilla.redhat.com/show_bug.cgi?id=760042 *** This bug has been marked as a duplicate of bug 741964 *** |
Created attachment 532626 [details] Stacktrace of a gnome shell crash during search Description of problem: After pressing ALT-F1 I enter a search term in the right upper field to start and application. gnome-shell crashes with SIGSEGV. Version-Release number of selected component (if applicable): gnome-shell-3.2.1-2.fc16.x86_64 How reproducible: Everytime Steps to Reproduce: 1. Press ALT-F1 2. goto search field (right upper corner) 3.enter something Actual results: gnome-shell crashes Expected results: application icons open Additional info: The crash is caused by dereferencing a NULL pointer in function _shell_app_match_search_term when it is used at line 1405 in the strstr() call. I implemented a band aid, attached as patch to this ticket which resolved the problem. I'm not sure if I really caught the root cause.
