Bug#618304: audacity: 99% CPU load, when nothing loaded in the program

[Jari Aalto]

Package: audacity
Version: 1.3.12-14
Severity: important


SUMMARY

If audacity is left open without any project in it, after some time,
it starts consuming all the CPU (see 99%).

     PID USER     PRI  NI  VIRT   RES   SHR S CPU% MEM%   TIME+  Command
   21375 root      20   0  703M  213M  7816 R 99.0  3.1 44h09:38 audacity

WHAT HAPPENED

- Edit about 10 projects (record audio, kill project; <repeat>)
- Remove all projects (the opening frame is blank)
- Have it sit "idle" on the Window manager [Gnome] (here 44h).

The high CPU loads are exhibited (> 90%).
