Bug ID: 407642
Summary: KFileWidget selects the the wrong filter on filter
change with enabled automatic extensions
Product: frameworks-kio
Version: 5.54.0
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Open/save dialogs
Assignee: fa...@kde.org
Reporter: glo...@fbihome.de
CC: kdelibs-b...@kde.org
Target Milestone: ---
Created attachment 120135

Simple test file picker program
If your filter list has two matching filters for an extension, KFileWidget will
always select the first filter, even if the current filter already matches the
file name.
The result is that a user selects a filter and it's not honored by the UI. This
resulted in two bugs in LibreOffice with the KDE backend:
* https://bugs.documentfoundation.org/show_bug.cgi?id=125267
* https://bugs.documentfoundation.org/show_bug.cgi?id=120950
Our workaround is now to ignore the returned filter string.
This bug doesn't happen with the non-native QFileDialog.
STEPS TO REPRODUCE
1. Compile and run the attached program
2. Make sure that "auto extension" checkbox is enable
2. Select the last file filter (DocBook (.xml)) via dropdown list
OBSERVED RESULT
Filter is "Word 2003 XML (.xml)"
EXPECTED RESULT
Filter is "DocBook (.xml)"
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Debian Buster with KIO 5.54
I already have a patch for this.
