QGIS 3.8.1 crashes when opening pop up from GetFeatureInfo

[JohannaOtt]

How to Reproduce

1. Add a WMS Layer to your project that supports GetFeatureInfo
2. The one I am using contains a link/button which leads to a pop-up showing up in QGIS 3.6.3
   This is the button how it is displaying in 3.6.3:
   
   This is the pop-up that is showing up:
   
3. Clicking on the same button in QGIS 3.8.1 it leads to QGIS crashing with the following stacktrace:
   Crash ID: 79a5865aaea4475b45aaff8427309b561233a3dd

Any URL we can try?

Hi,

Thank you for your quick reply. You can test with https://test.haleconnect.de/ows/services/org.8.15e341e4-5af1-4985-81ea-ac0376af82df_wms?SERVICE=WMS&REQUEST=GetCapabilities&VERSION=1.3.0

You will see that the link is already displaying different from the screenshot I made with QGIS 3.6.3 and clicking on the link causes QGIS 3.8.1 to crash.

All the best
Johanna

Confirmed on Linux/Master, thank you for the test WMS, please leave it online for a while.

@elpaso a new ticket should be opened regarding the fact that the identify panel does not render anymore the button (as shown in one of screenshots in this ticket)? Or is not a QGIS problem? Or it was already addressed by your patch?

[elpaso]

it's also fixed by my patch
