Do you have third party plugins installed? And does that also happen if you disable them?

comment:3 by lutra, 14 years ago

can you post also the wms you are using in order to make tests locally? layer list would also help.

Replying to jef:

I had lots enabled. I have disabled all plugins except for plugin installer and the crash has not occurred again (yet). After disabling the plugins, I closed QGIS and multiple errors came up referring to one of the OSM-related plugins. Since restarting all seems OK.

Looking at the backtrace it might be the autosave plugin. Can you verify?

It does indeed seem to be the autosave plugin. I enabled it and whammo, a while later it crashed. I think any relationship to WMS loading might be a red herring. So, what next?

So, what next?

send an e-mail to the author of the plugin and/or to the qgis-dev mailing list.
