SUMMARY When I open any pdf attachment from email in okular, close the attachment and exit Kontact, I can't open the program again. It opens only after some time, around 3 minutes. Once it opens I can close it using "X" icon, only from File->Exit. When start from terminal I see following messages: ommand= "okular %U" args= ("okular %U", "file:///tmp/messageviewer_attachment_tnBtct/Zajęcia piątek 16.04 NUTKI.pdf") EXEC "/usr/bin/okular /tmp/messageviewer_attachment_tnBtct/Zajęcia piątek 16.04 NUTKI.pdf" EXEC done sleeping for 180 seconds before deleting file... After closing the Kontact window, process does not terminate but remain in the process list. After 3 minutes I see message: 180 seconds have passed, deleting "/tmp/messageviewer_attachment_tnBtct/Zajęcia piątek 16.04 NUTKI.pdf" Removed empty parent directory "/tmp/messageviewer_attachment_tnBtct" STEPS TO REPRODUCE 1. Start Kontact 2. Open pdf attachment in the email 3. Close the pdf attachment 4. Close the Kontact program 5. Start Kontact program again OBSERVED RESULT Fails to open again quickly, but only after 3 minutes. EXPECTED RESULT Should open immediately.
