transmission-gtk 2.77 has a rather annoying preferences corruption bug in the 'downloading' tab. Opening the tab results in it's download dir settings getting corrupted and this can eventually result in the full settings file getting corrupted with non-UTF-8 characters. I've reopened an upstream bug at https://trac.transmissionbt.com/ticket/5246 (at this time still waiting for moderation), with a patch. Reproducible: Always Steps to Reproduce: 1. open transmission settings menu->edit->prefernces 2. switch to downloading tab 3. set 'save to location' 4. close the dialog 5. repeat step 1 & 2 6. the location is set to 'None' usually, can be anything, this is the moment the corruption happens
Created attachment 345914 [details, diff] patch to fix transmission-gtk preferences corruption Patch to fix issue by connecting the settings callback after the widget is already created.
2.80 in portage, has this patch, I've checked
