Reproducible: Always

Steps to Reproduce:
1. Go to: Settings - configure digikam - database
2. The database path be /home/photos
3. click after /home/ and enter: "horst/"
Actual Results:  
The path now reads;
/home/hPhotosorst/

Expected Results:  
The path should read:
/home/horst/Photos
Comment 1 caulier.gilles 2014-05-20 11:18:28 UTC 
Widget used to edit Database path is KUrlRequester from KDElibs :

https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/libs/widgets/common/databasewidget.cpp#L99

Problem is reproducible here. there is nothing special in digiKam code about

Sound like a problem from KDELibs...

Comment 2 Christoph Feck 2014-05-20 12:01:27 UTC 
I cannot reproduce it using the KUrlRequester that are used in System Settings > Account Details > Paths. Does it also happen there?

Can you please right-click the widget and check which "Completion mode" you use and try changing these?
Comment 3 qqqqqqqqq9 2014-05-20 12:08:34 UTC 
No problems in systemsettings for me. Changing the text completion mode doesn't have an effect.
Comment 4 Christoph Feck 2014-05-20 12:14:20 UTC 
Gilles, could you re-check digikam code? Does the code connect to the textChanged() signal, and if yes, what does it do?
Comment 5 caulier.gilles 2014-05-20 12:31:09 UTC 
yes, it's connected to textChanged() to filter path entered by user :

https://projects.kde.org/projects/extragear/graphics/digikam/repository/revisions/master/entry/libs/widgets/common/databasewidget.cpp#L236

Perhaps i need to use a timer here before to complete filtering and prevent slot cal for each characters enter in edit field ?
