This back trace is at the very beginning of qlmanage's launch, so even before it knows anything about your plug-in. This really seems like a bad bug that you should report to Apple. I'd be curious to know exactly how you invoke qlmanage under Guard Malloc (and with what exact version of the OS) as I can't reproduce that problem.

I'm trying to write a QuickLook plugin using Xcode, but I kept getting some really weird results - every time the plugin would execute, the QuickLook daemon would log thousands of malloc warnings to the console, completely overwhelming syslogd.
So I debugged it, and some very weird things were going on with the memory (e.g. view bounds were returning -NaN right after they were properly initialized). I tried it again with Guard Malloc turned on, and Guard Malloc would keep crashing in _LSCopyInfoForNode, called whenever qlmanage started up.
The backtrace is:

I saw someone else already had this problem last month - <http://lists.apple.com/archives/xcode-users/2008/Jul/msg00977.html> - but when I tried to reset the Launch Services cache (both using lsregister and manually), it did not fix the problem. I also tried deleting my QuickLook plugin, and the crash still happened.
Does anyone know what's going on here? How can I fix this?
