Send a OpenGPG encrypted mail
wit a attachment (.pdf) (or other).
and or receive the mail.

go to send folder or, if received, to inbox folder.
double click on the attachment.

normally it should now open it inside
the (pre)selected program. (evnice or okular)

but nothing happens.

right click on the attachment and "save"
is working normal. open inside this
menu did also nothing.

if sending a not encrypted mail
with attachment (.pdf) (or other)
it works as it should and will be opened
inside the selected program (evince or okular)

this happens always since update from 20240905.
20240905 was working.

i should mention, that since about more than one year
when i have opened files like described above
on the desktop for the time of opening, a temporary
symbol was shown, but i could not say if it was only
when the mail was encrypted or always.

with this new effect, not opening at all, maybe
something with temporary saving the file went wrong.
(i never touched the settings and did not know where to
search for)

i have this effect on 5 more or less similar tumbleweed
systems.
i have a other more or less similar system i have not
direct access and the operator there told me he has
not this new effect, but i could this not really verify,
and the operator is not somebody i would trust in using
a computer (nor clicking at the right place).
