-------------------------+------------------------------------------
 After auto-updating to 9.0 on Debian Buster with KDE Plasma, I got an
 error message popup instead of the "connect" window when starting that
 said something about my profile not being readable.

 However I only saw the message when clicking somewhere into the popup
 window and copypasting the text - as the window was just a black
 rectangle, nothing visible except the KDE-Plasma-styled titlebar and
 window frame.

 After closing the window and retrying to start Torbrowser several times,
 every Window was just all black, both the connection and the browser
 window. I tried re-installing both 9.0 and an older 8.0.3 to the same
 location and removing all mozilla/torbrowser related files in various
 locations (~/.local/share, ~/.mozilla, ~/.config/) which didn't help, the
 windows stayed black.

 Torbrowser is installed to ~/.local/share/torbrowser/tbb/x86_64/tor-
 browser_en-US, it was originally installed using the debian torbrowser-
 launcher packet from stretch-backports and patched forward until now.

 Interestingly, extracting the torbrowser download to a different location
 and running it in that fresh install location doesn't have black windows
 anymore and seems to work normally. Of course then my config and addons
 are gone.

 Might be related to some apparmor problems; however, removing the
 torbrowser-launcher packet which should change apparmor configs doesn't
 help.
