Crash when Using Tools->Scan For (Added|Removed) ROMs->For All

[Craig]

Launchbox 9.0, 9.1, 9.2 (all Launchbox.Next) When using Scan for (Added|Removed) ROMs LB allows one to select For All which appears to be an invalid Key to the XML "DB", or is just not properly used. All Platforms is what we mean to use. and that works correctly.

Steps to Reproduce:

1. Open Launchbox

2. Select
   Tools->Scan For Removed ROMs->For All or Tools->Scan For Added ROMs->For All

3. Encounter Crash

Expected Behavior - No Crash and the same result as All Platforms.

Traceback for Removed:

The given key was not present in the dictionary.

May be a dupe of Issue #4440 and Issue #4424

Also potentially would fix Issue #4403

Hi Craig, I'm having trouble pinning this one down. Can you zip up and email me your LaunchBox\Data folder? You can email it to [e-mail]. Thanks!

[Craig]

I just installed a new copy of Launchbox 9.2 on a virtual machine. Updated process below, screenshots, and Data Folder sent as requested.

1. Open Launchbox
2. Set the "view mode" to Platforms (Not Platform Categories, The Default view on initial install)
3. Select Tools->Scan For Added->For All
4. Crash.

Thank you Craig; I have this fixed for the next beta. Thanks for the detailed info. :)

Glad I could help. Looking forward to testing when the new final build comes out.
