Description Steven Franzen 2015-09-09 18:10:14 UTC 
I had a script residing in the mentioned directory to set some environment variables for Intel compilers. It did this by calling a script in the compiler directory with the right arguments. After uninstalling these compilers, this script was obviously no longer present, and I could no longer seem to start a Plasma session.

Reproducible: Always

Steps to Reproduce:
1. Have a script in ~/.config/plasma-workspace/env referencing a non-existent file.
2. Attempt to start a Plasma session.

Actual Results:  
Splash screen displays (if enabled), but progress bar does not fill. Otherwise a black screen with the mouse cursor.

Expected Results:  
The desktop session is started as expected.

.xsession-errors

The only contents of .xsession-errors upon encountering the bug.
Comment 2 Luca Beltrame 2015-09-10 07:28:29 UTC 
If you have the contents of the script handy, it would be good to have it here for testing.

The offending script

This is the offending part from the script.

Pushed by davidedmundson into branch 'Plasma/5.4'.

Continue even if script returns errors

/bin/sh stops execution upon finding a nonzero exit code,
which means that startkde will not continue if a script in
.config/plasma-workspace/env/ produces an error.

This small fix will execute a no-op in such a case,
so that errors will not affect startkde's progress,
while still being visible in .xsession-errors.

Comment 5 Rex Dieter 2015-10-06 01:31:53 UTC 
This fix broke env processing for us (fedora),  source'ing the items in subshell means the environment changes cannot propogate to the parent shell.
Comment 6 Martin Steigerwald 2015-10-10 12:59:42 UTC 
I can confirm this. Reopening.
Comment 8 Martin Steigerwald 2015-10-10 13:15:10 UTC 
Thanks, Bhushan. Confirmed that fix works in Debian Sid with dash as system shell.
