[Digikam-devel] Digikam Crash from Assert in libexiv2

Fri May 21 21:53:41 BST 2010

Hi,

I'm getting a digikam crash everytime I try to start up digikam (and it
scans my files.)

It's in libexiv2 (SVN from today, May 21, 2010.)

I've tried looking some but would appreciate any pointers.  It looks
like the write fails but I'm not quite sure what's being written (TIFF
metadata to where?)

I have lots of diskspace both on the image and SQLite database
filesystem (the same local disk.)

I added debug and see that the group name is CANON and sv is four more
bytes than what was returned as having been written (I don't have that
debug in this trace since I just updated exiv2.)

I suspect it's the same file each time but am not sure how to get the
filename from inside the exiv2 code.

The last few lines of the stdout/stderr and stack backtrace are below.

If anyone has any suggestions for debugging this I'd appreciate it.

Thanks,

Todd Goodman
