Bug#275959: dia --export-to-format= does nothing, hides errors

[Tommi Virtanen]

Package: dia
Version: 0.94.0-2

Dia's --export-to-format= option does nothing; it still tries to deduce
the format from the filename.

Also, even if dia aborts with error, it exits with status 0. This is
bad.


$ dia --export-to-format=png --export=overview.dia.png.tmp overview.dia
