Closed axet closed 7 months ago

Running 'gdu -d' first time causing a crash. Second run, works fine.

gdu 5.22.0-1+b1 (debian 12)

Thanks for your report. I think I have found the root cause and fixed it.

axet commented 7 months ago

I know how to reproduce the issue:

1) gdu -d 2) scroll down to the last entry 3) press down again 4) hit enter

Thank you! That helped a lot. I have found the real root cause and fixed it.
