libavifile problem

After updating my debian unstable a few days ago, loading avi files
with gephex does not work anymore.

Here is the error message that I get when I load an avi with the
frbinmodule:
|>

~  <codec keeper> : WARNING: plugin /usr/lib/avifile-0.7/ffmpeg.so could
~   not be opened: /usr/lib/avifile-0.7/ffmpeg.so: undefined symbol:
~     _ZN3avm18PluginGetAttrFloatERKNS_9CodecInfoEPKcPf
~   <codec keeper> : CreateVideoDecoder(): Unknown codec 0x58564944 =
~      "DIVX"
~   @error@ [mod_frbinmodule]:> Could not load file

<<

Here is my current understanding of the situation:

~  * /usr/lib/avifile-0.7/ffmpeg.so does not contain the definition
~    of the symbol (avm::PluginGetAttrFloat).

~  * /usr/lib/libaviplay.so does contain the definitions

~  * ffmpeg.so is dynamically opened with dlopen() in libaviplay.so
~    (in lib/codeckeeper.cpp of the avifile source)

~  * the authors of libavifile seem to assume that the plugins
~    (and with them ffmpeg) can access the symbols of the
~    library that dlopens them

~  * frbinmodule is linked dynamically to libaviplay.so
~    (via the run-time linker)

~  * frbinmodule is dynamically opened inside gephex-engine with
~    dlopen()


It seems that because of this complicated setup, the symbol
avm::PluginGetAttrFloat can not be resolved.
I tried various things without success:

~  * compiled the original libavifile release (had to patch some
~    things to make it work)

~  * created the debian packages from the debian source package

~  * added -export-dynamic to the LDFLAGS of gephex-engine and
~    frbinmodule

~  * tried to open all modules in gephex with RTLD_GLOBAL
~   (gephex crashes)


The thing I don't understand is why it worked before!
What changed in the new debian package? I don't know, the
changelog does not mention anything substantial.

Does anybody experience similar problems?
I would be very thankful wether loading avis works for other
people (also on different distributions/platforms).

Thanks,

Georg
