did it work before today?

And please, start amarok with 'amarok -d -nofork' from a terminal, your backtrace is not useful.
Comment 3 sc 2009-10-04 16:44:12 UTC 
amarok:  [ERROR!] GREPME MySQL query failed! Lost connection to MySQL server during query  on  "mysql_ping failed!"

I see this right before the crash.  I am able to connect to my MYSQL server outside of amarok.

I am not certain if this is a better backtrace:

Comment 5 Jeff Mitchell 2009-10-04 18:19:23 UTC 
Yeah, I'm aware there's some problem. I'm working on trying to figure it out; otherwise I may just revert those patches. It kind of seems like mysql_ping doesn't behave the way the docs say it does.

Also, I did make a change not long ago...do be sure you do a git pull.
Comment 6 Mikko C. 2009-10-04 21:10:52 UTC 
*** Bug 209442 has been marked as a duplicate of this bug. ***
Comment 7 Myriam Schweingruber 2009-10-04 21:38:34 UTC 
There is a valid backtrace in the duplicate bug 209442, btw...
Comment 8 Jeff Mitchell 2009-10-06 02:16:22 UTC 
Should have been fixed yesterday...sorry, forgot to update this BR.
