Arch Linux

Description:

After some update kmplot starts showing only the coordinate grid, no menu, status or toolbars. Findings:

* if I remove the file ~/.config/kmplotrc then kmplot starts properly
* if I close kmplot and start it again, it again starts with missing GUI
* explanation: kmplot generates a broken ~/.config/kmplotrc leading to the problem
* when placing a working kmplotrc (I have saved from another machine where I didn't run kmplot since the last updates), it is overwritten with a broken one when kmplot is started, on the next run it therefore starts without GUI
* diff between working and broken kmplotrc:

$ diff .config/kmplotrc_broken .config/kmplotrc_working

Additional info:
* kmplot version is 18.04.2-1 but downgrading to one of the earlier (working) versions doesn't help, looks like some dependency causes the problem



Steps to reproduce:
update your machine to the latest state, run kmplot
