Sample incomplete jpeg (10.78 KB, image/jpeg)
2004-05-20 16:52 UTC, Morten Welinder 		Details

Description Morten Welinder 2004-05-20 16:50:10 UTC 
When current gnumeric displays http://www.gnome.org/~gman/namethefilm.xls,
it ends up creating an incomplete jpeg image.  That is gnumeric's problem,
of course, but it reveals a gdk-pixbuf problem:

Sample incomplete jpeg

Sample file that is sent to gdk_pixbuf_loader_write.
Comment 2 Matthias Clasen 2004-08-12 03:51:04 UTC 
Loads flawlessly for me, valgrind shows nothing.
Comment 3 Matthias Clasen 2004-12-16 17:58:55 UTC 
Can you provide a testcase which shows the problematic behaviour ?
Comment 4 Morten Welinder 2004-12-16 18:09:14 UTC 
I did, in comment #1.

Here's the current barfage from gnumeric under purify when inserting that
truncated image.  I'm not sure if the jpeg_CreateDecompress is relevant.

Comment 5 Matthias Clasen 2004-12-16 18:12:45 UTC 
Note that I was asking about a testcase, as in a small c program, as opposed to
a) a stacktrace or b) test data, since I couldn't reproduce the problem with my
test programs (see comment 2)
Comment 6 Morten Welinder 2004-12-16 18:40:08 UTC 
"gdk-pixbuf-csource foo.jpg" will do.
