X crashes on plugging/unplugging USB mouse

[Morgan Collett]

Binary package hint: gdm

Running Natty - 11.04, upgraded from 10.10 on Apple MacBookPro5,3

gdm package version is 2.32.1-0ubuntu3

When I plug in/out my USB mouse (MS Intellimouse Explorer), X crashes and I get back to the gdm login screen.

In /var/log/syslog I see:

Thank you for taking the time to report this bug and helping to make Ubuntu better. However, your crash report is either missing or challenging to deal with as a '.crash' file. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer.

 If you are running the Ubuntu Stable Release you might need to enable apport in /etc/default/apport and restart.

 If you are using Ubuntu with the Gnome desktop environment - launch nautilus and navigate to your /var/crash directory and double click on the crash report you wish to submit.

 If you are using Kubuntu or Xubuntu you can file the crash using /usr/share/apport/apport-qt --crash-file=/var/crash/_my_crash_report.crash in a terminal - where _my_crash_report.crash is the crash you would like to report.
 I'm closing this bug report since the process outlined above will automatically open a new bug report which can then dealt with more efficiently. Thanks in advance for your cooperation and understanding.
