Invalid value entered in Open List of Files Dialog

KPhotoAlbum crashes when a invalid file name is provided in the Open List of Files window

1. Open KPhotoAlbum
2. Click on Edit
3. Click on Open List of Files...
4. Enter an invalid file name (for example just the letter "a" or "1" or "not-a-valid-file.jpg")
5. Click OK
6. KPhotoAlbum crashes


No crash; KPhotoAlbum should ignore invalid value.

Linux: openSUSE Tumbleweed 20230807; Kernel Version: 6.4.8-1-default (64-bit)
KDE Plasma Version: 5.27.7
KDE Frameworks Version: 5.108.0
Qt Version: 5.15.10
KPhotoAlbum Version 5.11.0 (as installed from Opensuse Tumbleweed repository)
Also occurs in latest git version v5.11.0-51-gc9fc8883

1. Crash is reproducible every time the steps are followed.
2. Crash does not occur if the invalid file name has the "/" directory separator
3. Crash occurs even if the first file name is valid but the second file name is invalid. In this case Clicking OK in step 5 does not crash; however, clicking the empty second thumbnail in thumbnail view causes the crash.
4. Crash occurs even in the demo database

Comment 1 Tobias Leupold 2023-08-10 05:25:55 UTC
I can reproduce this using the demo database. I never used this feature, so I have to have a look what happens here ;-)

Comment 3 Victor Lobo 2023-08-10 22:35:41 UTC
Thank you! While testing the fix I noticed an edge case scenario which still causes the crash.

Scenario is:
1. File exists on the disk, and
2. File exists under the KPA image root directory, but
3. File does not exist in KPA database

Where #3 could be due to
a. File exists in a directory under the KPA root but is excluded from new file search (via Settings).
b. File has recently been added to KPA root and rescan has not been done.
c. File exists under the KPA root but is not an image file.

Easiest way to reproduce the crash in the fixed version is via 3.c: 
i.  In the demo database enter "index.xml" without the quotes as the filename in Open List of Files.
ii. KPhotoAlbum crashes.

Thanks for the quick feedback! Should be really fixed now...

Thank you! Fix looks good.
