Comment 3 Michal Hlavinka 2016-11-14 10:30:10 UTC
Hi,
you've reported several similar abrt crashes. They are all caused by curses module. It does not have proper error codes/messages so it's difficult to say what went wrong. Most often these are false positives. It happens when you run iotop in a terminal and close that terminal. In that case, iotop is still running, it tries to write output to terminal which does not exist and crash is reported. Is it your case too? Did abrt pop up after you've closed the terminal? Or did it really crash? Can you reproduce this problem?

no, terminal is running but iotop stop running.
yes, abrt notify me that iotop is crashed.

Comment 5 Michal Hlavinka 2016-11-14 15:21:20 UTC
Are you able to reproduce this? How long iotop runs before it crashes? What terminal do you use?

no, i'm not able to reproduce it at the moment.

run time is different, not always the same.

i'm using xfce4-terminal with tmux running correctly on top.

Comment 7 Fedora End Of Life 2017-07-25 23:07:44 UTC
This message is a reminder that Fedora 24 is nearing its end of life.
Approximately 2 (two) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 24. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '24'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 24 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Comment 8 Fedora End Of Life 2017-08-08 17:28:04 UTC
Fedora 24 changed to end-of-life (EOL) status on 2017-08-08. Fedora 24 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
