I already posted this on the IRC channel, but here on mailing it's more appropriate.

While trying to send crash-reports this morning, report-gtk stoped working, several times.

report-gtk killed by SIGABRT  / 
crash_function: __libc_calloc  /  
package: libreport-gtk-2.14.0-4.fc33  /  
component: libreport
Kernel 5.8.3-300.fc33.x86_64  / 
Plasma 5.19.4  /  
kde frameworks 5.73.0  /

My installation is a F33 kde upgraded yesterday with dnf-plugin-system-upgrade

thanks
