Runtime error in mtaction.cpp

Hi. I am getting a runtime error when runniung a (long) action. Error appears once for every file being processed. Running as admin does not help. Acknowledging the error allows the action to continue and it seems to complete successfully. I can't find any errors in the action itself (although I am not an expert). Shortening the action doesn't help. Updating to latest version did not help. Generating new cfg file did not help. Hope you can help.Thanks.

PS. Sorry in advance if I am being stupid!

Please upload the action file and not the copied text.
Also, please use the upload function in this forum and not some 3rd party hoster.
And: have you tested which of the steps leads to the error - it would be quite nice as it could be that the error appears only in a certain environment or with certain files.

This looks like a hand-crafted action group and not something Mp3tag has created via its UI. In particular, there is a rogue [#14] on line 67, which breaks the parsing.

Please try and check the files for errors, especially if you edit them outside of Mp3tag.
