You have been subscribed to a public bug: I've encountered this problem while investigating crash in amarok-kde4 beta1, but this affects every package in my Kubuntu Hardy distribution (x86_64).
I suppose the contents of .gnu_debuglink section in all packages are invalid, therefore gdb fails to load symbols even if appropriate -gdb packages are installed (which makes them useless): On my Kubuntu: # objdump -s -j .gnu_debuglink /usr/lib/libQtGui.so.4.4.0 /usr/lib/libQtGui.so.4.4.0: file format elf64-x86-64 Contents of section .gnu_debuglink: 0000 6c696251 74477569 2e736f2e 342e342e libQtGui.so.4.4. 0010 30000000 000101b1 0....... Note, that this is not libQtGui.so.4.4.0.debug shipped with libqt4-dbg On Fedora 8: # objdump -s -j .gnu_debuglink /usr/lib/libQtGui.so.4.3.3 /usr/lib/libQtGui.so.4.3.3: file format elf32-i386 Contents of section .gnu_debuglink: 0000 6c696251 74477569 2e736f2e 342e332e libQtGui.so.4.3. 0010 332e6465 62756700 0607bf23 3.debug....# Note that this points to .debug file name which is installed with appropriate debug package. I can confirm this for libqt4* 4.4.0-1ubuntu5~hardy1 packages and seems every other. Because of this bug I can't step into calls to libqt4 functions (But the main probelm is that I can't get useful backtraces to file crash reports).
