Bug ID: 515040
Summary: Okular blocks on startup by probing Recent Files on
unavailable network paths
Classification: Applications
Product: okular
Version First 25.12.0
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
If Okular’s Recent Files list contains documents located on a mounted network
share, starting Okular while the network is unavailable or unstable causes very
long startup delays or apparent hangs.
This happens even when:
Okular is started without opening any document, or
Okular is started with a local PDF file.
The user has not clicked any recent file, but Okular still probes them during
startup.
Other PDF viewers (e.g. SumatraPDF, Adobe Acrobat Reader) show recent files but
do not touch them until explicitly selected.
STEPS TO REPRODUCE
1. open remote file on mounted path
2. close okular, disconnect network
3. open another local file or just blank okular
OBSERVED RESULT
Okular startup hangs while checking recent files.
strace shows blocking filesystem access to a recent network path:
$ strace okular ./test.pdf
...
access("/home/user02/SambaShares/company/printer/office01-printer/2026-01/Untitled_20260113_132614.pdf",
F_OK) = <hangs>
EXPECTED RESULT
Okular should display Recent Files without accessing them on startup like
SumatraPDF.
Network paths should only be accessed when the user clicks a recent entry.
As user
I sometimes need recent network files when connectivity is restored,
so removing Recent Files entirely is not an acceptable workaround.

ADDITIONAL INFORMATION
As a user, I am usually aware when the network is unavailable or unstable (e.g.
while traveling train, bad hotel wifi) and deliberately avoid opening
network-backed recent files.
However, Okular still accesses those paths automatically on startup, causing
unnecessary blocking and poor usability in such situations.
