Previous version Qt4.4.1 commercial edition was working using attached font file (pl_PL.ttf). Now on Qt4.7.1 this font file causes a segmentation fault. My currently released application (QT4.41) uses this font no problem, when the user changes language I add the font to the QFontDataBase and use the new font.I would like to continue using the same fonts after upgrading to Qt4.7.1 since my product is released already. I attached an example that causes this. In the Attachment the ko_KR.ttf works, the pl_PL.ttf does not. Here is the debug output from the program.

• • DEBUG START **
    THIS IS THE FONT THAT WAS ADDED "/usr/local/resources/fonts/pl_PL.ttf" "Sansation"
