Fwd: Crash in 0.9 SVN with Exiv2 0.10

[Gilles Caulier-2]

Duncan,

I suspect a digiKam linking problem. Like you have merged both Exiv2 version
(0.9.1 and 0.10) in your system before, i recomend you to clean up properlly
all using make distclean (better way is to remove all local source code
repository and re-checkout from scrach...

Also, I'm using also a Dynax 5D here with a lot of MRW files (around 500
here). I cannot reproduce the crash here on my computers (3 speed computers
in my office, and my laptop and my host computer at home).

The crash come from the digiKam startup and mix the editor plugin and the
internal Exiv2::minolta makernote. Of course these implementations are
complety independant (the image plugins do not use Exiv2), but at the digiKam
startup, the albums collection is parsed to find new items (if you have
checked the right option in setup of course)

I suspect that a MRW file is parsed and sometihng is wrong in memory, and make
alterations in current image plugin loaded in memory.

Andreas, i forward this message for informations... If you have ideas, let's
me hear... Also, like you use digiKam now in your computer, can you reproduce
this problem ?

Gilles

Using tagged Exiv2 after Gilles pointed out that 0.9.1 wasn't right in my ldd
output.  Now digikam crashes on startup.  Fresh build from this morning.

$ ldd /usr/bin/digikam | grep exiv
        libexiv2-0.10.so => /usr/local/lib/libexiv2-0.10.so (0xb78f0000)

KCrash: Application 'digikam' crashing...

Rather annoying, as I was trying to narrow down why digikam was writing
corrupt jpegs from mrw files.

I've just nuked all presence of digikam, kipi plugins and exiv2 from my
machine, including source code.

I've recompiled exiv2, kipi plugins and digikam - the crash occurs in the same
place.

I'm at work right now, so I'll have to tackle this in bits and pieces, or I'll
tackle it when I get home.

I think I may have missed a library somewhere.

Nuked /usr/lib/kde3/kipi*, started digiKam, worked.
Closed digikam.  Reinstalled kipi plugins.  Started digikam.  Worked.

Time to update my scripts even more to nuke anything in existence that might
be related to digikam when I'm doing svn compiles :)
