See below.

[rajika@localhost bin]$ ./lqpl -c 0.9.0 lqpl: Common/src/Utility/Extras.lhs:19:26-60: Irrefutable pattern failed for pattern (bname, _ : ext)

[rajika@localhost bin]$ ./lqpl -l 1 0.9.0 lqpl: Common/src/Utility/Extras.lhs:19:26-60: Irrefutable pattern failed for pattern (bname, _ : ext)

I think rather than giving a source stack a useful error message should be given to user(in case a required command line option is missing).
