[Synaptic-devel] Synaptic 0.45pre7 : found a way to crash it

[Guillaume Pratte]

Here is to crash Synaptic 0.45pre7 :

1. Open Synaptic :-)
2. Select an upgradable package and open the "Advanced" tab.
3. Go in the preferences dialog and change the default release (e.g. in my 
case : from unstable to testing).
4. In the "Advanced" tab of the currently selected packaged, select another 
version.
5. "Segmentation fault".

In GDB :

Program received signal SIGSEGV, Segmentation fault.
