Gpick crashes when exporting

[Ytrog]

Whenever I export the palette Gpick crashes.

I caught the following when I launched it from the commandline:

terminate called after throwing an instance of 'std::logic_error'
  what():  basic_string::_M_construct null not valid
zsh: IOT instruction (core dumped)  gpick 

I tried with both css and txt formats.

Version: 0.2.6
OS/Distro: Manjaro

Not very useful, however you may see something I don't:

(No debugging symbols found in gpick)
