Crash on Ubuntu 10.4

[tonyarmitstead]

I just built/installed the latest 1.6.0 and had a crash when changing the output directory.
The console crash dump was:
tony@fromroom:~/makemkv_v1.6.0_bin$ *** glibc detected *** makemkv: free(): invalid pointer: 0x08a85190 ***

I tried again after posting and it did not crash on my second try.

My usage sequence was not exactly the same the second time - so it does not appear to be just changing the output folder which triggers the crash. It may depend on previous operations.

I will try again to reproduce.

I got it to crash again

I couldnt see a core file - it was not in my current working directory. The GUI seems to crash but the makemkvcon process is still sleeping. 'ulimit -c unlimited' does not help me. Where should the core file be created (does the program change its current directory)?

However I think I know what to do to trigger the crash. In the GUI, I click the button to change the output directory. The directory I specify in the GUI (am using gnome) is one that is on a currently unmounted disk (I use a large NTFS drive to rip to and it has not been mounted yet, but the GUI lets me select it from the Places list - which appears to then mount it). When I click the Open button the crash occurs.

Once the disk has been mounted - either by the previous directory select operation (prior to the crash) or by me manually mounting it before running makemkv, the crash does not occur.

It's a QT bug. We have no control over it You'll have to submit bug to ubuntu.
