Description John Wells 2007-07-31 04:19:04 UTC

Steps to reproduce:
1. Select Import from File menu
2. Select Canon Digital IXUS 750 (PTP mode) from Input Source menu
3. Watch f-spot go horribly down in flames.
4. Worth noting that both Digikam and gThumb work fine with same input source.

I'm able to import via gThumb and then import into F-Spot from files, but this is for my wife switching from OS X to Linux, so not ideal at all.

Comment 1 Bengt Thuree 2007-11-21 18:53:35 UTC

Shouldn't this one be reported mainly on libgphoto?
http://www.gphoto.org/proj/libgphoto2/

Or should we push them to get a resolution on this issue?

Comment 2 Tim Retout 2007-12-27 00:09:31 UTC

Also reported at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=315484

It's worth noting that import via gThumb worked, so it shouldn't be a libgphoto2 issue - perhaps f-spot's bindings. It's also the case that all three reporters were using PPC machines.

To me this sounds similar to (but different from) bug #505822.

Comment 3 Tim Retout 2008-04-24 11:25:05 UTC

Retitling to make it easier to find.

Comment 4 Ruben Vermeersch 2010-06-08 07:40:34 UTC

Gphoto2-sharp is no longer used in git (we use gvfs now), so this should be fixed. Could you test this?

Comment 5 Tim Retout 2010-06-11 10:11:57 UTC

I've still got a PPC box, although we don't have an easy test case for this bug, do we?  I mean, one that doesn't involve a Canon Digital IXUS 750 in PTP mode.

Comment 6 Ruben Vermeersch 2010-06-11 10:16:42 UTC

Not that I'm aware of. But we're not doing any magic related to gphoto2 anymore: we delegate that task to gvfs. So from an F-Spot point of view, this bug should no longer exist. If it fails, it'll probably be a gvfs bug now.

Just asking for testing to be sure, rather than immediately closing the bug. If you are able to test this, please do so, otherwise we should probably just close it.

Comment 7 Tim Retout 2010-06-11 13:21:10 UTC

In that case, please assume I can't test this.  Even if the bug still exists (which it shouldn't), the stack trace would be entirely different, so I'd just close this bug.  It's easier than remembering to come back in a few weeks.

Comment 8 Ruben Vermeersch 2010-06-11 14:24:54 UTC

Okay, closing! Thanks!
