The second backtrace seems to be linked to on screen notification

[SDERAWI (sderawi-deactivatedaccount)]

3rd Crash >>> When clicking on an RSS item.

The application '<unknown>' lost its connection to the display :0.0;
most likely the X server was shut down or you killed/destroyed
the application.

Regarding the first backtrace, which seems to happen on calling an external application. Could you tell me what external app you are calling?

The output
mv: target `3/Finished' is not a directory

Seems to suggest that the external program is not used properly and it may be the origin of the crash.

[SDERAWI (sderawi-deactivatedaccount)]

mv: target `3/Finished' is not a directory

was fixed by escaping the space before the 3 >>> "TERABYTE 3" or TERABYTE\ 3 , but the crash happened after that also.
