Sorry.the examples of bug descriptions are in italian in my installation, so I have supposed I can write in italian language.

However,I was importing some photos by scanner when digikam crashed. Digikam crashed creating the preview of the second photo.

At restart, digiKam has worked fine and I could continue the import without any crash

thanks

No problem :-)
Comment 4 caulier.gilles 2011-03-13 12:12:58 UTC 
Andi, it's a libksane issue...

Comment 5 Kåre Särs 2011-03-14 12:27:35 UTC 
Hi,

Strange if it was in the middle of a preview... the crash is in createOptInterface which is called by open device. Unfortunately the variables that could give me some hints of what is wrong are optimized out :(

Is this crash repeatable?

Gilles: I wonder about the multiple:
"Backtrace stopped: previous frame identical to this frame (corrupt stack?)"

Could that have something to do with it?

Comment 6 caulier.gilles 2011-03-14 12:45:31 UTC 
If crash is due to a memory leak, valgrind can help a little bit.

Else, trying to get another backtrace in same condition can give more info.

Of course all must be compiled with full debug info. If crash is due to a shared lib like libsane, without debug info, no more details can be get by crash handler

The duplication is probably the other way around ...  but it should be fixed :)
