[Bug 1562477] Re: apport-retrace crashed with TypeError in error(): not enough arguments for format string

[Benjamin Drung]

Thank you for taking the time to report this bug and helping to make
Ubuntu better. This kind of bug can still appear since apport still has
code like "fatal(str(error))".

** Description changed:

  Retracing the crash of window-buttons applet produced this error.

+ ```
+ Traceback (most recent call last):
+   File "/usr/bin/apport-retrace", line 301, in <module>
+     options.dynamic_origins)
+   File "/usr/lib/python2.7/dist-packages/apport/sandboxutils.py", line 204, in make_sandbox
+     apport.fatal(str(e))
+   File "/usr/lib/python2.7/dist-packages/apport/__init__.py", line 35, in fatal
+     error(msg, *args)
+   File "/usr/lib/python2.7/dist-packages/apport/__init__.py", line 44, in error
+     sys.stderr.write(msg % args)
+ TypeError: not enough arguments for format string
+ ```
