Package: xine-ui
Version: 0.99.3-1
Severity: normal
The "mrl play" network command segfaults if used when xine first
starts up. I'll append a stack trace.
The segfault is caused by the dereference of gGui->playlist.mmk in the
call to gui_set_current_mmk(), as it is NULL. Fixing this in the obvious
manner (

play" with an empty playlist after applying this patch, I get this
strange error:

There's an accompanying popup on the screen ("The specified file or mrl
is not found. Please check it twice. (There is no mrl.)"). The real MRL
(jerry.avi) does play in this case.
Here's the stack trace for the unpatched version.
