Hello, i hope, i did it right. I toke this wiki for the Backtrace: http://wiki.debian.org/?HowToGetABacktrace First i downloaded and installed all the sources for compiling per aptitude. After this i compiled the sources with this: DEB_BUILD_OPTIONS=nostrip dpkg-buildpackage -us -uc Then i installed the package via dpkg. After this i run gdb with the following command: gdb xfce4-appfinder At the gdb-prompt i type this commands: set pagination 0 run It shows the same error *** glibc detected *** free(): invalid next size (fast): 0x08092550 ***
Here ist the complete output from the gdb in the shell: "gdb xfce4-appfinder GNU gdb 6.4.90-debian Copyright (C) 2006 Free Software Foundation, Inc.
