[Bug 303218] New: digikam import crashes when you select video files

James R. Shipman
https://bugs.kde.org/show_bug.cgi?id=303218

            Bug ID: 303218
          Severity: crash
           Version: 2.6.0
          Priority: NOR
          Assignee: [hidden email]
           Summary: digikam import crashes when you select video files
    Classification: Unclassified
                OS: Linux
          Reporter: [hidden email]
          Hardware: Fedora RPMs
            Status: UNCONFIRMED
         Component: general
           Product: digikam

Application: digikam (2.6.0)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.4.4-5.fc17.x86_64 x86_64
Distribution: "Fedora release 17 (Beefy Miracle)"

-- Information about the crash:
- What I was doing when the application crashed:
I had just imported jpeg/tiff files, then clicked on "video files" to look at
my movies because I don't get thumbnails of movies and the import tool does not
remember which movies have already been uploaded.  I can't easily tell which
movies have already been uploaded because there is no information displayed
about mp4 metadata and no thumbnail.

The crash can be reproduced some of the time.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/usr/lib64/libthread_db.so.1".

Thanks in advance

Actually the crash you're talking about is a different one. The given codepath
does not exist at all in recent version of digiKam because the filtering is
commented out in import ui and that FilterCombobox is not used elsewhere at
all.

That doesn't mean that there's no crash inside that code, but it'll need to be
debugged when the filtering is restored.

This crash now happens after import while digikam is scanning for metadata in
the background.  Exiv2 crashes whenever it runs into a file that it doesn't
understand and this brings digikam down with it.

I reported this to the exiv2 bug tracker and they said that M2TS (MTS) video
files were not suppoted by exiv2 and digikam should not have called exiv2 for
unsupported file types.  They put my bug in as a "feature request" with low
priority.

Right now I can't run digikam because right after it starts (idle to me, but
scanning metadata in the background) it crashes because of exiv2.

digikam would be much more robust if it would trap these kind of exceptions and
recover instead of simply crashing.  You will always be vulnerable to crashes
by your dependencies unless you trap them and handle them yourself.

digikam would be much more robust if it would trap these kind of exceptions and
recover instead of simply crashing ==> crash must be handle properly in low
level interface (Exiv2). After all, Exiv2 know better which files can be
managed or not...

I close it as UPSTREAM (relevant of Exiv2)
