Severity: important
X-Debbugs-Cc: emmanuel.farhi at synchrotron-soleil.fr

Dear Maintainer,

   * What led up to the situation?

Starting command 'dioptas' (or Desktop launcher) fails.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?

An error message is displayed , and the program stops:

<class 'ValueError'>:
Unable to convert ffffff to QColor

Dioptas Version: 0.5.2

   * What was the outcome of this action?

The GUI should start. It does not.

   * Potential solution: upgrade to upstream Dioptas 0.5.5 or 0.5.7 as reported
in https://github.com/Dioptas/Dioptas/issues/133
