Comment 14 for bug 331742

Back to the original problem, as reported in post #3 and #7. The fact is that in many cases, we can successfully test a task by clicking "Run selected task", but then, in real life it won't run.
Two main technical reasons:
1) The test is PATH-aware, the real task (using cron) is not
2) The test is insensitive to the output mode ("Default" or "X application"), the real task is not

I think this is indeed a bug worth to be fixed.
At least, the message that appears when testing a task should be improved ("Note about working directory of executed tasks", it is confusing.) Additionally, the "Run selected task" function should be improved.
