Description Alexander Potashev 2017-07-17 23:11:37 UTC 
plasmashell crashes on image drag'n'drop from Telegram onto folder containment.


Steps to reproduce:

1. Download and run the official Linux GUI client for Telegram: https://desktop.telegram.org/
2. Send/receive and image in Telegram (you can e.g. send an image to yourself).
3. Configure desktop as a Folder containment.
4. Drag the image from Telegram onto the desktop.
--> plasmashell crashes!

Dolphin does not crash in the same scenario involving Telegram, it just does nothing.


=== plasmashell crash backtrace: ===

I tried these steps, but Folder View won't actually let me drop a Telegram image ...

Comment 6 Alexander Potashev 2020-03-08 12:48:03 UTC 
In 5.17.4 the Folder View containment does not let me drop an image from Telegram. Anyhow, it doesn't crash anymore.
