Bug#857931: gsequencer: AgsSynth possible division by zero by oscillator

Joël Krähemann-2
Source: gsequencer
Version: 0.7.122-2
Severity: important

Dear Maintainer,

The user can select a frequency of 0 what leads to a division by 0.
This causes a SIGSEGV and the application gets killed.
The application shouldn't crash at all.
