nautilus crashed with SIGSEGV in PyThreadState_New()

[Gavin Chappell]

Binary package hint: nautilus

I just upgraded my laptop from Karmic x64 to Lucid Alpha 2 x64 (via sudo do-release-upgrade -d). All packages installed with no errors, after the first reboot and booting into Lucid's kernel, I logged in and was told that Nautilus had crashed. My taskbar has repeated "Starting File Manager" windows (4 at the moment, although it will occasionaly drop down to three, I don't know whether this is the oldest instances of these timing out or the newest one opening and closing repeatedly) even though I haven't asked Nautilus to open. Also my mouse cursor is constantly in the spinning "busy" state.

If I click on Places->Home, I just get an "Opening gavin" window in the taskbar but no Nautilus window opens up.

I just noticed that once I closed all my open windows, my desktop background still appears to be that of the gdm login screen, I can't right click it, and the folders on my desktop are invisible (although still on the filesystem). Is nautilus still responsible for rendering the "desktop" as a clickable, interactive entity? This may explain why nautilus was crashing even though I hadn't actually opened any nautilus windows.

[Gavin Chappell (g-a-c)]

My mistake, I thought I'd removed any unnecessary PPA software before I release-upgraded. However, I'd forgotten that I recently installed groundcontrol from DoctorMo's PPA. I've now purged this and nautilus is working correctly again.

Thanks for the report, is this still an issue with latest package on Lucid?

[Gavin Chappell (g-a-c)]

I haven't tried reinstalling Ground Control to replicate the bug after removing it in my last report, if that's what you're asking.

If you or doctormo would like me to do so and test it, I can do this for you however.
