Description

Copy&Pasting an image from Firefox looks to paste something in the textbox, but upon sending Quaternion crashes with an assert failure: ASSERT: "!plainText.isEmpty() && !htmlText.isEmpty()" in file /.../client/chatroomwidget.cpp, line 428

Steps to reproduce

  • Copy an image, test from a web page
  • Paste in Quaternion chat field
  • Hit ENTER to send

Ideal behavior would be to convert the paste into an image upload, like Element does. However, not crashing, or even just outright rejecting an image paste, would also work.

Adding some printf debugging to ChatEdit::insertFromMimeData(), I see the following:

hasHtml: true hasImage: true

html: "<meta http-equiv="content-type" content="text/html; charset=utf-8"><img class="avatar avatar-user" src="https://avatars.githubusercontent.com/u/1408010?s=52&amp;v=4\" alt="@chmeeedalf" width="26" height="26">" -- end

"html: " and " -- end" being added by me as delimiters.

Quaternion dumps logs to the standard output. If you can find the logs and
identify any log snippets relevant to your issue, please include
those here (please be careful to remove any personal or private data):

ASSERT: "!plainText.isEmpty() && !htmlText.isEmpty()" in file /.../client/chatroomwidget.cpp, line 428

Check for image MIME data before HTML data
2942642 
Copying an image from Firefox attaches some HTML to the image.
Extracting the plain text from the HTML before the image results in
empty data in the field, with no image, triggering an assertion failure
on message send.

This is a partial fix for issue quotient-im#867.  Partial, because the resulting
image does not appear in the chat window until relaunching, due to an
error opening the temp file created by this.
