When trying to delete a character in edit mode, Noteedit crashes.
Can you try running noteedit under valgrind and report the crash
information provided that way?
To run it under valgrind, start it like this on the command line in a
terminal:
valgrind noteedit
I do not know much about noteedit, but do know how to debug crash
bugs. :)
Happy hacking,
Hallo Petter,
I am really very amazed, but today I couldn't reproduce the bug (haven't
applied noteedit for a longer time now). Perhaps the bug was caused by
kde libs that meanwhile have been updated. When I sent the bug report
noteedit behaved in the descripted way (also after restarting the
computer). However, I send you the output of valgrind (not completely
because the terminal swallows the first part and the command "valgrind
noteedit >> noteedit.txt" didn't redirect the whole output into that
file, only three lines).
Thanks for your efforts and I will further have a look if the bug comes
back or if it is reproduceable in special situations.
Best regards
Benedikt Bock
