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:
#0 0x92f31a21 in _LSCopyInfoForNode
#1 0x92f4e8cb in LSCopyItemInfoForURL
#2 0x93dc2750 in CGSNewConnection

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?
