[arch-general] Qsynth crashes when clicking on buttons (Don't Panic)

[Nigel Henry]

Hi Folks.

When I open Qsynth, I can rotate the various controls, but clicking on any of 
the buttons causes it to crash. For example I click on the "Options" button, 
the options window opens momentarily, but is blank, then Qsynth goes out to 
lunch.

When Qsynth is opened without messing with the buttons, Qjackctl shows 
fluidsynth available as an input port, so that bit is working ok.

Starting Qsynth on the CLI gives me this output, see below.
[djmons at myhost ~]$ qsynth
Warning: no locale found: /usr/share/locale/qsynth_en_US.qm
Segmentation fault
[djmons at myhost ~]$

I'm totally clueless about locales, but could this be the problem? Looking 
in /usr/share/locale there is no en_US locale. There are a bunch of en 
locales though (en, en at boldquot, en at quot, en_CA, en_GB)

Looking at when I started Qsynth on the CLI as above, it shows a segfault, but 
the GUI for Qsynth is still showing. It's only when I click on a button that 
it crashes.

Can anyone confirm that they have Qsynth working as expected?

I don't want to post a bug report if this problem has something to do with 
locales on my install.

Thanks for any help on this problem.

Nigel.
