Description 20120808_bugs.kde.org 2010-03-21 13:14:27 UTC 
Application: konqueror (4.4.1 (KDE 4.4.1))
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.31-20-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
I was viewing tables in phpmyadmin through konqueror. I was attempting to change the charset and collation defaults. Made the changes to mysql then restarted mysqld. Apparently I had typed something wrong because it seemed the server was not running. Nonetheless I refreshed the phpmyadmin page in konqueror. Doing so resulted in a page from pma indicating that the collation type I had entered was wrong and that the server (mysqld) had gone away.
Next konqueror crashed and here I am filling out this drkonqi bug report.

 -- Backtrace:
Application: Konqueror (kdeinit4), signal: Segmentation fault

Dear Bug Submitter,

This bug has been stagnant for a long time. Could you help us out and re-test if the bug is valid in the latest version? I am setting the status to NEEDSINFO pending your response, please change the Status back to REPORTED when you respond.

Thank you for helping us make KDE software even better for everyone!
Comment 5 20120808_bugs.kde.org 2018-10-30 19:19:43 UTC 
As far as I can recall, I only ever noticed the crash the time reported here in this ticket. According to the comments, the crash was not even reproduced when attempting to acquire the crash with valgrind on the lookout.
Comment 6 Andrew Crouthamel 2018-10-31 03:39:51 UTC 
Thanks for the update!
