Problems with IM

Hi,

after trying to install the latest version of IM parallel
to the one that comes with Ubuntu, I think I kind of
messed this up. (I deleted the new install in the meantime,
after compiling it, and installed the old version (6.5.1)
via Synaptic (I am using Ubuntu "Karmic").

When I try to perform a simple 'display', I am getting
the following error messages:

display: UnableToOpenConfigureFile `delegates.xml' @ 
configure.c/GetConfigureOptions/589.
display: NoDecodeDelegateForThisImageFormat `weisser_alarm.png' @ 
constitute.c/ReadImage/531.
display: UnableToOpenBlob `logo:': <??? @ blob.c/OpenBlob/2481.

Does anybody have an idea how I can fix this? (please,
note the strange characters in the last line. I have the
impression that there's something the matter with the
character encoding in my Ubuntu install in general, but
I'm not actually quite sure about that.

TIA,

Claus
