segaafult after typing a single character in a dilogue

Kmymoney crashes(segfaults) in many dialogues, including typing in fields like payee, or new institution, or beginning to fill out the dialogue for an entirely new file. Perhaps I have some library problem, but other KDE based programs have no such issues?
Comment 1 Christoph Feck 2017-06-08 00:45:15 UTC
The backtrace reveals no information. Do other Qt4 based applications work?

I had tried some KDE apps with no problem, but in response to your question, I tried opening "QT4 designer" and as soon as I type there is a segfault. So this must not be just a kmymoney problem. My apologies, thank you.
Comment 3 Thomas Baumgart 2017-06-09 06:05:31 UTC
Would you mind sharing the information (backtrace) of that Qt Deisgner crash here as well? They might be related to KMyMoney, that is why I am asking for it.
Comment 4 Phillip Renner 2017-06-09 13:15:10 UTC
I experience similar crashes with kmymoney, rekonq and KeePassX on a text input with the first key down. I will attach the backtrace frm rekonq. KeePassX doesn't open the KCrash handler. Platform openSUSE Tumbleweed.

Backtrace rekonq segfault after first key down on text input
Comment 6 p.com 2017-06-10 12:47:17 UTC
When I run QT designer and hit a key, it segfaults, but the crash handler doesn't open. I tried running it through strace, but it didn't look very interesting to me. I also have keepassx and tried that, it has the same problem. Let me know if there is something I can do to add information.
Comment 7 Christoph Feck 2017-06-13 18:55:05 UTC
Backtrace from comment #5 for rekonq is identical to the kmymoney4 crash from comment #1, in other words, the creah looks unrelated to kmymoney4.

I suggest to report this issue to the bug tracker of your distribution. If you do, please add the link here.

Thomas, time to release the KF5 port ;)
Comment 8 Wolfgang Bauer 2017-06-13 19:24:20 UTC
This is a general problem with Qt4 and ibus in Tumbleweed currently.
See http://bugzilla.opensuse.org/show_bug.cgi?id=1043734

Workaround: uninstall or disable ibus
