100% CPU usage with SVN trunk

[Mark Kretschmann]

Hi guys,

a user was reporting 100% CPU usage with SVN trunk today. User says CPU usage 
increases shortly after startup, and never goes back. Now, check the first 
line of the debug output he sent:

"QObject: 605 timers now exist for object QObject::unnamed"

Looks like we create a timer repeatedly without deleting it? 605 timers could 
explain high CPU usage, I guess. (BTW, this shows how useful it could be to  
give all QObjects a proper name, instead of keeping it unnamed!)

Any ideas?
