 Tor Browser adds few additional environment variables which breaks
 `kdialog` and likely other applications also:

 {{{
 FONTCONFIG_PATH=/home/user/tor-browser_en-
 US/Browser/TorBrowser/Data/fontconfig
 LD_LIBRARY_PATH=/home/user/tor-browser_en-US/Browser/TorBrowser/Tor/
 }}}

 originally reported against QubesOS.])

 Perhaps do not modify environment variables for applications launched from
 Tor Browser?
