Empty MainWindow pane on start-up in FC34 dev venv. #779

Closed tparchambault closed 1 year ago

tparchambault commented 1 year ago

This is over the older FC34 platform however this may be the issue that @egbicker has also observer over FC37.

My current git branch where this issue was observed was forked off of the current master with the recently introduce async trust feature. The issue was not observed after switching to the local branch, fa688_improve_error_loggingthat had not been merged locally with the latestmaster.`

UnpopulatedTrustViewAtStartUp

tparchambault commented 1 year ago

Although, the MainWindow was unpopulated, mouse events were handled such that I could change to a different tool view and continue working via the GUI.

Thanks @tparchambault , this is a bug in the trust check.

This gave it away

BatchConf: tc:0, tl:0, bc:0, bl:0

The case of no trust entries is not being handled properly.

Ill send a fix up. In the meantime add an ancillary entry manually and see if it fixes it.
