Bug ID: 489834
Summary: Action opening attachment fails with "Invalid
environment block." due to environment variable of
third party software
Classification: Applications
Product: kmail2
Version: 6.1.1
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: commands and actions
Assignee: kdepim-b...@kde.org
Reporter: cookie...@web.de
Target Milestone: ---
SUMMARY
openSUSE Tumbleweed, up-to-date. Wayland session. A software called midnight
commander is installed. I sets an environment variable
BASH_FUNC_mc%%=() { . /usr/share/mc/mc-wrapper.sh
}
_=/usr/bin/printenv
This may or maybe not posix conform. But since update to a recent version of
Plasma6 this variable prevents kmail from opening an attachment. OK, after
reading this sentence again, I have to admit that I guess that the variable is
the cause for the kmail malfunction. However, after I uninstalled mc, kmail
works as expected.
After starting kmail on command line and clicking on an attachment in kmail to
make it open a pdf e.g., the error message there is:
kf.kio.gui: Failed to launch process as service:
"app-org.kde.okular@6af406497e054a04a6adc583bf0242da.service"
"org.freedesktop.DBus.Error.InvalidArgs" "Invalid environment block."
STEPS TO REPRODUCE
1. Install midnight commander
2. reboot
3. open kmail and try to open an attachment to an email, a pdf e.g.
I reported that bug here as well
https://bugzilla.opensuse.org/show_bug.cgi?id=1227388
I regard that behaviour of kmail as a bug, because even the environment
variable set by mc is somehow wrong, kmail should be immune to such errors.
Besides that, isn't this even a security risk, if any other software which sets
a wrong variable can cause kmail to malfunction?
OBSERVED RESULT
Error message
EXPECTED RESULT
Okular opens displaying attached pdf
