Hey Pavel,

I'm curious about what is causing this. As far as I can see we do not use QMatrix in our source code. On Linux, the translation unit for Track.o does not show any use of QMatrix symbols either.

Could you please run `find . -name "*.o" -exec sh -c 'objdump -t $1 > $1.txt; grep -Hn QMatrix $1.txt' {} {} \;` in amarok/utilities/collectionscanner/CMakeFiles/amarokcollectionscanner.dir? You'll find that directory in your build directory. The exec part scans all the generated object code of the amarokcollectionscanner target for QMatrix symbols.

If objdump is not available for you, please re-try with elfdump or plain dump instead.

Thanks a lot.

- Kevin
