Description temp 2022-05-16 10:52:06 UTC 
SUMMARY
***
Dolphin creates temporary files in /tmp when thumbnailing image files from "smb:" mounts (r/w or r/o).
Over time, these files fill /tmp
eg:
-rw------- 1 ubuntu ubuntu        0 May 16 11:38 dolphin.ExHKzo
-rw-rw-r-- 1 ubuntu ubuntu  8577350 May 16 11:38 dolphin.ExHKzo.part
-rw------- 1 ubuntu ubuntu        0 May 16 11:38 dolphin.IeQYAj
-rw-rw-r-- 1 ubuntu ubuntu 14409948 May 16 11:38 dolphin.IeQYAj.part

***


STEPS TO REPRODUCE
1. Ensure 'preview' is set to enabled for remote files in dolphin
2. Open smb mount - eg smb://192.168.1.11/photos2022_RW/3_Mar/
3. Observe as thumbnails are generated increasing number of files in /tmp/ - these are never removed

OBSERVED RESULT
-rw------- 1 ubuntu ubuntu        0 May 16 11:38 dolphin.ExHKzo
-rw-rw-r-- 1 ubuntu ubuntu  8577350 May 16 11:38 dolphin.ExHKzo.part
-rw------- 1 ubuntu ubuntu        0 May 16 11:38 dolphin.IeQYAj
-rw-rw-r-- 1 ubuntu ubuntu 14409948 May 16 11:38 dolphin.IeQYAj.part

EXPECTED RESULT
No objection to files being created in order to thumb - but should be removed post thumbnail

SOFTWARE/OS VERSIONS
Linux/KDE Plasma:

ADDITIONAL INFORMATION

Comment 1 Paul Worrall 2024-09-02 18:42:20 UTC 
I'm seeing this too.  
It's not difficult to fill up /tmp by browsing a photo collection via the smb kioslave. 
Should this bug be reassigned to the kioslave?
