~/.trinity/tmp does not exist on my system.

I have ~/.trinity/tmp-hostname instead, which is a symlink to /tmp/tmp-username.

There I see the following files after having successfully created and edited 
three files from konqueror with kedit on the remote server:

  27 2017-11-13 14:29 kdesktop_lock_lockfile
  68 2017-11-13 14:48 kedit36IMvK.tmp
   0 2017-11-13 14:46 kedit3mLdZy.tmp
   0 2017-11-13 14:46 kedittcniZ0.tmp
   0 2017-11-13 14:46 keditYZCbBb.tmp
 520 2017-11-13 14:47 konqueror-crash-ajNlMO.log
   0 2017-11-10 13:08 krusader1igmPB.tmp
   0 2017-11-06 13:28 krusader9on97Z.tmp
   0 2017-11-07 15:55 krusaderZcrD9O.tmp

The konqueror crash log seems to report about opened and closed connections to 
the remote server.

Hope this helps.

Regards,
Stefan
