Filename issues when downloading documents with scan_postbox

[megamorf]

Hey, thanks for this very useful library. I used it for the very first time today and one of my primary use cases is to grab new documents from the postbox.

I encountered the following issues with the downloaded documents:

Edit: the problematic files have the following names in the postbox and this is the corresponding download link:

Let me know how I can help you get these two issues resolved :-)

Hi, I pushed a fix into the master branch which should address the umlaut encoding. The "zero lengh" issue is a bid trickier.

• Are these PDF documents?
• Are you able to replicate the problem? If so can you please download the latest devel branch, enable debugging, replicate the issue and send me the logs?

I reran the download based on master 7b49fa61893d0dc6084b3aa2898f457cca0de9c5 and it not only fixed the umlaut encoding problem but also seems to have fixed the zero length document problem.

The only difference this time is that I had to run dkb.scan_postbox(PATH, download_all=True) since all the documents from the previous run had been marked as read and there's no way to mark them as unread again.

Thank you for your response. Good that the zero-file size problem seems to be addressed as well (even if I do not fully understand why). The change made into v.18. Thus, I am closing this issue.
