Confirmed on rev 27602 (Windows XP)

Just tried to reproduce under as well Linux, no crash there.

Blender trunk revision 27667

Linux 2.6.31-20-generic #58-Ubuntu SMP Fri Mar 12 04:38:19 UTC 2010 x86_64 GNU/Linux

Hi, I managed to reproduce the crash under OS X. The crash is actually inside libjpeg, not blender.

It's interesting that your linux version worked ok though. The libjpeg for OS X in blender's svn is v6, I updated to v8 locally, but still got a crash.

What version of libjpeg do you have on your linux system?

Tried it again (svn trunk 27837) and it worked perfectly.
I can even activate "Show image files" in the "open .blend" dialog without crash.

One new thing that I missed in my last try - Blender doesn't crash, but actually reports an error message:

=================
Corrupt JPEG data: 3582 extraneous bytes before marker 0xd9
Premature end of JPEG file
libpng error: Image width or height is zero in IHDR
Corrupt JPEG data: 2380 extraneous bytes before marker 0xd9
Premature end of JPEG file
libpng error: Image width or height is zero in IHDR
=================

Not sure why it's reported as a "libpng error"?

System version of libjpeg:
libjpeg62 6b-14build1

Thanks, a few more questions: On what OS did it work perfectly on the last try? Windows or Linux?

Which OS gave the error message? Does the error message appear on both OS versions? Are these versions that you compiled yourself, or pre-built ones from online?

Strange that the linux libjpeg is relatively old too, and works ok...

Oh, I'm sorry, I forgot to mention:
Whenever I tried it on Linux (version -> see my previous message) it worked fine (and printed the error message).

On Windows XP it crashed like reported in the bug report.

I didn't SEE any error messages on Windows because the console did close itself before I could check.
So I'm not sure if there is the same error yet.
Unfortunately I can't check on Windows again, since I don't have a Win installation where I am right now.

Closed a report which I think is the same as this one: [#21810] Image browser crashes with incomplete JPG files

Attachment from that report is Archive.zip, and backtrace is here:

Hi,

The crash is in libjpeg, so nothing that we can do (if libjpeg is fixed and return a NULL pointer or some class of error that we can check...)

No point to keep this open, not a Blender bug.
