Bug#756257: goplay: SEGV when clicking on PACKAGE/DESCRIPTION headings

[Russell Coker]

Package: goplay
Version: 0.5-1.2
Severity: important
Justification: renders package unusable

I recompiled goplay to fix bug #755404 (a basic recompile is all that's
needed).

One one of my test systems goplay displays no packages (for unknown reasons)
and will SEGV when I click on the title of the main list box (where it says
"PACKAGE" and "DESCRIPTION".  On another of my test systems it displays a list
of packages and operates correctly apart from a SEGV if you click in that
area.

The backtrace is below.  I'll attach a screen-shot showing where to click for
a SEGV.

Program received signal SIGSEGV, Segmentation fault.
