Hello and thanks for reporting this issue.

The crash seems to be caused by a problem in our Parser. Do you mind sharing the textbundle file here or in private for tests?

3

the textbundle file was sent by mail. thanks for response.

4

Sure I don’t mind. please check the attached. it’s a note with some special characters in it I’d guess.

(Attachment Python CHP NOTES.textbundle.zip is missing)

5

sorry I have to try resending the file with ‘.md’ suffix due to the email upload policy. please change the extension back to .zip and uncompress then get the .textbundle.

Python CHP NOTES.md (2.64 MB)

Thanks a lot. Luckily Panda’s development version can open the textbundle (but not version 2952). The error was probably connected to an URL parsing bug we recently fix. This and other bug fixes will come with the next update as soon as possible.

You’re welcome. Sure. I’d retest it when new beta is out.
