Hi Ansa,

I haven't been able to reproduce this crash or the others linked. But you mention using stylesheets, and I think that could be the difference. Sadly, I haven't been able to figure out how to apply these stylesheets. Could you maybe help?

I drag images from Dolphin to the Image toolbar in Parley. Every now and then, this leads to Parley and Dolphin crashing simultaneously. Is this a parley bug, a Dolphin bug, both, or none? (I only realised that the crash is simulatneous now that it happened again; I've been super busy all month, sorry for not replying earlier. Also, I thought I have answered the questions about using stylesheets, but now I see I haven't.)

How to use stylesheets:
the stylesheet is just a plaintext file similar to css. The documentation is here: http://qt-project.org/doc/qt-4.8/stylesheet-syntax.html
I am running Parley with a stylesheet called parley.qss, the content of which is just these four lines 

QPushButton:focus { 
  background-color:#C9DDF0; 
  border:5px solid #C9DDF0; 
}

Running parley with stylesheets is done as follows (it is listed in parley man pages among the Qt specific options, "parley --help-qt"). I have the stylesheet in a file called parley.qss on a flashdrive, in the same folder as the kvtml files; I put the images into a subfolder of this folder.

/usr/local/bin/parley --stylesheet /media/ansa/1D9D-9B1D/Jazyky_a_Parley/Parley/parley.qss
