Comment 2 Marcel Wiesweg 2010-06-05 22:31:47 UTC

Crash should be fixed. I dont close because I dont know why the task got stuck in the first place. Can you reproduce that? Which format? Simply missing progress info, or never finishing?

Comment 3 Johannes Wienke 2010-06-06 00:57:43 UTC

It really never finished. But I can't reproduce this right now. Was a normal 8 bit tif.

Comment 4 Marcel Wiesweg 2010-06-06 15:16:24 UTC

Reopen when anyone can reproduce.
