not much to go on to start the investigation.

looks pretty close to start up, and is probably one or just a few people contributing crash reports.

os breakdown
17      1       Windows NT5.1.2600 Service Pack 2

and all the reports were within the same hour

the png and image code doesn't appear to have changes for quite awhile, but maybe the network code under it changed recently.

guessing this will get buried in the ranking quickly, but we should keep an eye out.

Are these crashes still occurring? The "more reports" above link talks about
Windows SP2 and the "platform" field above says MacOS.  I've taken the bug
because it's PNG, but maybe PNG was an innocent bystander here.

Not enough to go on here. Resolving INCOMPLETE.  It's possible that the bug still exists but leaves a different signature now.
