Description Joel Uckelman 2009-01-23 13:31:01 UTC 
Created attachment 329832 [details]
a ZIP archive containing the offending ICNS file

Description of problem:

I was attempting to select an ICNS file as an attachment for Bug 481284, but every time I clicked on it in Firefox's file chooser dialog, Firefox immediately crashed. I suspect that this has something to do with attempting to create a preview to display in the file chooser dialog, and that something is failing catastrophically during that process. I've attached the ICNS file which makes this happen for me---but wrapped in a ZIP archive, since this bug prevents me from attaching the ICNS file itself.

As a side note, it made me chuckle to discover a bug whilst I was attempting to report another bug.

Version-Release number of selected component (if applicable):

firefox-3.0.5-1.fc10.x86_64

How reproducible:

Always.

Steps to Reproduce:
1. Go to a bug at bugzilla.redhat.com and attempt to add an attachment.
2. Choose the ICNS file attached to this bug in your file chooser dialog.
  
Actual results:

Firefox crashes.

Expected results:

The file should be selected. Firefox should not crash.
Comment 1 Matthias Clasen 2009-01-25 01:06:05 UTC 
That .icns file triggers an assertion in libjasper:

 jpc_dec.c:1072: jpc_dec_tiledecode: Assertion `dec->numcomps == 3' failed.

Aha! That's very interesting.(In reply to comment #1)

That's very interesting. This is precisely the same exception I was reporting in libicns (Bug 481284) when I found this bug. I didn't realize that this exception was coming from libjasper.

I can confirm that Firefox no longer crashes when selecting the INCS file, with this build of jasper. (There's still no preview in the file chooser, though.)
