I tried to debug, but ended at /usr/src/lyx/lyx-git/src/Exporter.cpp:142
FileMap::const_iterator cit = externalfiles_.find(format);
Here the log:

What I do not understand, why it->exportName references (incorrectly in my
eyes) /usr/src/lyx/lyx-git/lib/images/math-mode.pdf
although dest is set to /home/kornel/lyx/test/. (This is the dir where Math.lyx
lies)
Next try was to stop at Buffer.cpp:4134 (vector<ExportedFile> const files = ...)
only to stop at above mentioned Exporter.cpp.
Please help.
