Cool VL Viewer forum

(Linux Mint 21.3)
Suddenly any attempt to open a notecard from inventory with doubleclick results in this warning:
WARNING: LLView::createDummyWidget: Failed to create dummy widget of requested type (view) named 'SansSerif' in notecard
WARNING: ll_apr_warn_status: APR: Connection reset by peer
WARNING: LLPluginProcessChild::idle: Message pipe is in error state (104), moving to STATE_ERROR

hereafter the viewer (any version) quits with a segmentation fault.
I set NotecardEditorFont to RobotoMono-Regular to see if that makes a difference and it did not.

I guess something is wrong in the basic font setup of my machine but I have no idea....

This is the sign some XUI file got corrupted or out of sync... Are you using a custom skin, or custom fonts.xml file ?...
If yes, try mv -f ~/.secondlife/skins ~/.secondlife/skins-disabled from a terminal, reinstall the viewer from scratch (using its installer), and restart it...

If this does not work, post the zipped ~/.secondlife/logs/stack_trace.log and ~/.secondlife/logs/CoolVLViewer.log files for that crash.

This fixed it indeed! Thank you very much!
