Entering a "," in the name of a new item creates a corrupt entry

[bsandoz]

As the title says, entering a "," in the name of a new item (or seemingly any new data - spells, feats etc.) seems to create a corrupt entry which then makes it impossible to access anything which has this entry in it (character sheet, equipment list). An error shows in chat: "Parameternummer 2 "description" zur Funktion "json.get" muß eine ganze Zahl sein." (roughly translated: parameter number 2 "description" of function "json.get has to be an Integer).

To Reproduce
Steps to reproduce the behavior:

1. Go to a character sheet.
2. Click on Equipment -> Add New.
3. Enter a name that has a comma in it for the new item and save.
4. Item will not appear in the equipment list. After closing the character sheet, trying to reopen it will result in the mentioned error.
5. Trying to open Equipment -> Other in the compendium will result in the same error, as well as trying to access the equipment section in the settings menu.

I have tried to manually delete the corrupt entry in the Lib:compendium token's properties menu, but it did not solve the issue. Manually deleting the corrupt item from the character token's properties allowed me to access the character sheet again, but the other menus remain bugged.
