Theming error when converting SVG to PNG for email

[JUVOJustin]

I currently can´t send Emails via smtp because the Theming Add-On is causing a TypeError. After deactivating the Add-On everything is working as supposed.

Steps to reproduce

1. Activate Theming Add-On
2. Set SMTP Details via Interface or config
3. "Send Mail"

Expected behaviour

Test E-Mail Delivery with SMTP

Actual behaviour

PHP Error caused by the theming Add-On

GitMate.io thinks possibly related issues are #6784 (Php error?), #8740 (PHP errors (libpng)), #285 (PHP error in logfile), #1494 (legacy/image.php No error handling), and #8293 (PHP fatal error after running web updater).

Same issue. Just verified SMTP works after disabling Theming app..

[arnydo]

Both of our logs indicate issues converting the SVG file to PNG. Did you upload a SVG file to the theme by chance?

I replaced the SVG with a PNG and the error has stopped.

All is good now.

[kesselb]

Could you share the broken logo for easier debugging?

[JUVOJustin]

I can agree, that the error occured when using any svg file. it was not specific to a specific one.

Meanwhile i was able to solve the problem with completely removing and reinstalling the theming plugin.

[MorrisJobke]

cc @juliushaertl for the SVG to PNG conversion

[MorrisJobke]

What PHP extensions do you have enabled?

[kesselb]

I fixed the type error (#11610). Could you try again when Nextcloud 14.0.2 is released? Even when conversion from svg to png does not work the mail should be send.

[juliusknorr]

@JUVOWebDes @arnydo Can you check the output of the following command: identify -list format | grep SVG

It should output a list of supported SVG formats by the imagick library of your system:

     MSVG  SVG       rw+   ImageMagick's own SVG internal renderer
      SVG  SVG       rw+   Scalable Vector Graphics (RSVG 2.44.3)
     SVGZ  SVG       rw+   Compressed Scalable Vector Graphics (RSVG 2.44.3)
