Panel seems to crash when switching between open files in Kile

[Flansch]

The following steps describe the error:

- Opening Kile, it automatically restores the files that where open on last use.
- Switching to a different open file, either by clicking on the tab or using the Alt+Left/Right keys.
- About one second later the panel content disappears (except the program's title 'Kile') and the menu bar is integrated into the Kile program window.
- Another second later, the panel again fills up with it's original content (in serveral steps) and the menu is reintegrated into the panel.
- The same happens on opening or closing files (which automatically changes the selected file tab).

Flansch, thank you for reporting this and helping make Ubuntu better. However, your crash report is missing. Please follow these instructions to have apport report a new bug about your crash that can be dealt with by the automatic retracer. First, execute at a terminal:
cd /var/crash && sudo rm * ; sudo apt-get update && sudo apt-get -y upgrade && sudo apt-get -y install gnome-panel-dbg && sudo service apport start force_start=1

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

Now reproduce the crash, then open your file manager, navigate to your /var/crash directory and open the crash report you wish to submit.
If this fails you will have to open a terminal and file your report with 'ubuntu-bug /var/crash/_my_crash_report.crash' where _my_crash_report.crash is the crash you would like to report. If you get an error that you aren't allowed to access this report you will have to file it with 'sudo ubuntu-bug /var/crash/_my_crash_report.crash'. If you run the command against the crash report and a window pops up asking you to report this, but then never opens a new report, you would be affected by https://bugs.launchpad.net/ubuntu/+source/apport/+bug/994921 . In order to WORKAROUND this, one would need to open the following file via a command line:
gksudo gedit /etc/apport/crashdb.conf

and comment out the line:
'problem_types': ['Bug', 'Package'],

by changing it to:
# 'problem_types': ['Bug', 'Package'],

Save, close, and try to file the crash report again via:
ubuntu-bug /var/crash/_my_crash_report.crash

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.

Please do not attach your crash report manually to this report and reopen it.

Thank you for your understanding.
