When opening files in texteditor, Pfind opens symlinks, and not the real files. Lets change this for version 2.6. In Grafpup you are running multiuser. Do this give trouble with permissions in /tmp/?
If trying to open MANY files in Geany I got an extreme delay.
I just wonder: Could it be problem with filenames not compatible with UTF-8 charset. Max hits in Pfind 2.5 is set to 500. I guess you edited the config file. If running a low-powered system it's not recomended. The option ACCEPT_ARROW is because I experienced that < and > gave trouble when handling filenames from iso8859.1.once before I've had a search for "mp3" turn up 900 hits or something, but only a hundred and fifty or so showed up in the list, and the last entry was "/mnt/hdb6/", which has no "mp3", so something must have messed it up somehow.
