Error with recent bottle versions

[eht16]

When using web-pdb with bottle version >= 0.13, web-pdb will crash:

CRITICAL:root:Web-PDB: starting web-server on http://127.0.0.1:5555
Exception in thread Thread-1 (_run_server):

AttributeError: Attribute frame_data already defined. Plugin conflict?

I'm not sure if this is an issue in web-pdb or bottle though it seems to me the related code in https://github.com/bottlepy/bottle/blob/master/bottle.py#L1124 is pretty much on purpose.

On bottle version before 0.13 everything works fine.

I see the same issue and have the same experience in terms of old version working and new throwing this error.

Thanks for reporting this. Strangely enough, it does not happen in tests, and the line in question in the Bottle sources added long time ago.

Just hit into this issue so I can confirm that it occurs.

I met the same problem. I use python 3.8.20, web-pdb 1.6.2 and the bug disappeard when I changed bottle to 0.12.25

I also met the same issue. I use Python 3.11.0 and web_pdb 1.6.2 Is installing a lower bottle version will correct the problem (lower than 0.13)?

Fixed in 1.6.3
