Bug 211596

Application that crashed: kdevelop
Version of the application: 3.9.95 (using KDevPlatform 0.9.95)
KDE Version: 4.3.2 (KDE 4.3.2)
Qt Version: 4.5.2
Operating System: Linux 2.6.27-gentoo-r8 x86_64

What I was doing when the application crashed:
Just opened kdevelop and started modifying a class method then it crashed.  I was copying and pasting of a line of code that opens an ALSA midi port.
"port_out2 = snd_seq_create_simple_port(handle, "Output2", SND_SEQ_PORT_CAP_READ |
                                              SND_SEQ_PORT_CAP_SUBS_READ,
                                              SND_SEQ_PORT_TYPE_PORT );
"
