[jcom] Unable to store service provider record

[SniperSister]

I tried to update our service provider record. Editing works fine, however on save an exception is thrown:

 0 array_combine(): Argument #1 ($keys) and argument #2 ($values) must have the same number of elements

I got the same error today after I updated my service provider record and saved.
It displayed the error but the record was saved.
When I reopened my record and saved the item the second time, I did not get the error anymore.
