okular doesn't start if a mounted NFS directory is not available e.g. due to a network change. mount: example.org:/shares/media on /home/media type nfs4 (rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,clientaddr=192.168.1.156,local_lock=none,addr=192.168.1.22) strace shows it tries to access a file which was recently opened. I guess for the completion of the list of recent opened files. STEPS TO REPRODUCE 1. remove network cable 2. open okular 3. wait forever OBSERVED RESULT hangs forever EXPECTED RESULT 1. open the file / okular GUI immediately. 2. load the list of recent opened files with a timeout of 2 seconds. 3. load the list asynchronously in the background e.g. in a thread 4. log a warning message to stderr/elsewhere, if the files isn't accessible 5. ignore unreachable files (remove them from that list or grey them out) 6. maybe retry periodically (I don't care) 7. at least, always start fast!
