error importing photos with f-spot on ppc: LibGPhoto2.CameraFile.GetDataAndSize () -> Number overflow.

[fish]

Binary package hint: f-spot

The bug is every time reproducable:
After starting f-spot, selecting import and choosing the camera f-spot crashs.
Looks like the same bug already reported in the debian bugtracker: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=439816

When started in a terminal i get this error:

gphoto2 -P works well. Its just generating a warning about
setting file attributes (which is the same on all systems i use to
download photos from that camera):

Important: The import worked without problems on a x86 Notebook
(Thinkpad R51) with the same Ubuntu version and the same camera!
I guess that LibGPhoto2.CameraFile.GetDataAndSize returns a to large number on PPC...

I have exactly the same issue on my iBook G4, Canon SD1000. As with reporter, gphoto2 works fine, but f-spot crashes consistently with same traceback.

anyone tried to import with f-spot on hardy ppc beta?

does it still give the above error?

Cheers

Hi

I have just tested with hardy on ppc and I have exactly the same error.
My camera is a Canon Powershot A520.
I join the fspot log.

Best regards
Thomas

the new version fixing the issue is in intrepid

[Richard Wilbur (richard-wilbur)]

This is still a problem with fully updated Hardy LTS (8.04.2). Every time I plug a digital camera into my laptop (PPC) the first thing it does is crash F-Spot. I close the unhandled exception window and open gThumb manually which works great. I wish either:
1. Hardy LTS F-Spot were updated with this fix (I filed 582113 on Gnome bugzilla against v0.4.3.1 and was notified it had been resolved long ago, but in Intrepid), or
2. I could choose gThumb as the default handler when a digital camera is detected (it works great!).

Kind of embarrassing to have the main application crash every time I plug in a digital camera. With gThumb the digital camera support is simple and "Just Works." The Long-Term Support edition of Ubuntu (Hardy 8.04) is scheduled for support on the desktop till April 2011--two years from now.

[Richard Wilbur (richard-wilbur)]

I backported the fix from upstream for Hardy LTS (8.04.2) and the source is in my PPA at
 https://launchpad.net/~richard-wilbur/+archive/ppa
as f-spot_0.4.3.1-0ubuntu2~ppa1~hardy1

When I built and tested on my PPC it worked! What do I need to do to propose this as an update for Hardy LTS? I attach the pbuilder results for the powerpc (PPC) architecture as LaunchPad PPA won't build that binary. Test it and let me know your results.

[Onkar Shinde (onkarshinde)]

@Richard,

If you need to propose this fix as stable release update please refer to https://wiki.ubuntu.com/StableReleaseUpdates

You need to attach the debdiff between current version and the version you have prepared. Also make sure that your version has proper changelog entry i.e. release name hardy-proposed and appropriate version string.

[Risto Suominen (risto-suominen)]

I tested Richard's powerpc package on my iMac G4 and Ubuntu 8.04.1 (up-to-date). It solves the problem! Thank you, Richard! I hope they accept it as SRU.

[Richard Wilbur (richard-wilbur)]

Risto, thanks so much for testing the fix! I knew the crash problem on
f-spot was a bother for me. I am thankful this is open-source software
so I could fix the problem, but even more thankful it is "free" (libre)
software so I can share the fix with others.

Now, I need to get my fix in line with the SRU guidelines so it can be
released.
