Created attachment 68290 [details] Backtrace of the crashing client Without a pointer device (mouse) and under Weston-DRM, launching weston-terminal and typing a key causes an immediate SEGV in the client. This is not seen when Weston is run under X. Setting severity to ''blocker'' since there may be usage models where no pointer device is desired. Attaching backtrace and commit ids. Running with latest Fedora 17 kernel (3.5.5) and udev. NOTE: Running the client under gdb produces different behavior than without. When running under gdb, Wayland itself will SEGV as well. Without gdb, only the client terminates.

Could you attach the backtrace uncompressed, as text/plain, please? Compressed files are impossible to have a quick look in a browser. FWIW, the x11 backend always provides both kbd and pointer, regardless of actual devices, so that's why it doesn't crash there. When you say Wayland will crash, if the client runs under gdb, do you mean Weston? In that case, a backtrace of Weston might be interesting, too. Sounds like there is a bug in both. I guess that when the client is under gdb, it does not disconnect, and so Weston will have the opportunity to use some corrupted data before the client is destroyed. Thanks.
(In reply to comment #4) > Could you attach the backtrace uncompressed, as text/plain, please? I did already-- attempting to view shortly after upload gave me an unexpected internal server error, hence the subsequent bz2 upload. Fortunately, all seems to be sorted out, and the text/plain version can be viewed here: https://bugs.freedesktop.org/attachment.cgi?id=68292 > > Compressed files are impossible to have a quick look in a browser. > > FWIW, the x11 backend always provides both kbd and pointer, regardless of > actual devices, so that's why it doesn't crash there. > > When you say Wayland will crash, if the client runs under gdb, do you mean > Weston?

In the non-gdb case, weston-terminal (the 'client' referred to in bug description) will crash, and Weston will continue to run. When running gdb on weston-terminal or weston-terminal + Weston, but not when running on Weston alone, both terminal and weston will crash. Attaching bt of Weston in the crashing scenario as well. > > Thanks.
