Bug ID: 436708
Summary: MimeTypeFinderJob does not follow symlinks - causes
problem launching file manager
Product: frameworks-kio
Version: git master
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kio-bugs-n...@kde.org
Reporter: j...@keelhaul.me.uk
CC: kdelibs-b...@kde.org
Target Milestone: ---
SUMMARY
This can be demonstarted by trying to open a directory, either directly or via
a Type=Link desktop file, which refers to a symbolic link. The link is not
followed which means that an incorrect (or no) MIME type is returned. This
happens when launching such a desktop file from the Plasma desktop, but it can
be reproduced from the command line.
STEPS TO REPRODUCE
1. Set up test directories/symlinks as follows:
drwxr-xr-x 2 user users 40 May 6 20:46 /tmp/a/
lrwxrwxrwx 1 user users 1 May 6 20:46 /tmp/b -> a/
2. Execute 'kioclient5 exec file:///tmp/a'
==> The directory /tmp/a is opened in the default file manager
3. Execute 'kioclient5 exec file:///tmp/b'
==> No file manager is started
An error box saying simply "/tmp/b" is displayed
A debug message is shown:
kioclient KIO::MimeTypeFinderJobPrivate::scanFileWithGet()::<lambda: KIO::get
didn't emit a mimetype! Please fix the ioslave for URL QUrl("file:///tmp/b")
OBSERVED RESULT
Failure as in (3) above
EXPECTED RESULT
In (3) above the directory /tmp/b should be opened in the default file manager.
