To fix the underlying problem with ALSA, you need to load the ALSA sequencer kernel modules. For instance, you can run this command as root in a terminal: # modprobe snd-seq Anyway, I'm going to fix the ALSA backend of KMid to avoid the crash, showing a more informative text instead. Thanks for the report.
SVN commit 1143411 by pedrol: Avoid a crash at startup when loading the ALSA backend and the sequencer modules aren't available. This means two changes: - Ensure that compilation has "-fvisibility=default" instead of the "hidden" attribute, in addition to -fexceptions. - Catch generic exceptions in the backend constructor, in case that a distro overrides the compiler flags.
