Created attachment 67281 [details] New crash information added by DrKonqi kontact (4.7.4) on KDE Platform 4.7.4 (4.7.4) using Qt 4.8.0 - What I was doing when the application crashed: The same as original reporter - I selected "completion order" from the "to field" conext menu. I reproduced the crash many times, but not every time. -- Backtrace (Reduced): #7 0x00007f47b4910d54 in QObjectPrivate::deleteChildren (this=0x6766e50) at kernel/qobject.cpp:1917 #8 0x00007f47b3cc355d in QWidget::~QWidget (this=0x46a4f50, __in_chrg=<value optimized out>) at kernel/qwidget.cpp:1675 #9 0x00007f4758c2337c in ~ComposerLineEdit (this=<value optimized out>, __in_chrg=<value optimized out>) at /usr/src/debug/kdepim-4.7.4/messagecomposer/composerlineedit.h:31 #10 ~RecipientLineEdit (this=<value optimized out>, __in_chrg=<value optimized out>) at /usr/src/debug/kdepim-4.7.4/messagecomposer/recipientline.h:49 #11 MessageComposer::RecipientLineEdit::~RecipientLineEdit (this=<value optimized out>, __in_chrg=<value optimized out>) at /usr/src/debug/kdepim-4.7.4/messagecomposer/recipientline.h:49
I think I found the pattern. The crash happens every time when I start with a new mail, write some letters in the recipient field, then delete them and then select "completion order" from the context menu. It doesn't crash when: - I start with a new message and select "completion order" right away - I type some letters and do the above without deleting them first. The same happens when I select "edit last addresses".
I confirm it. Thanks for step. Will look at.
I might have a similar problem. When writing a new mail, I put the email address in and start typing the message, kmail crushes.

*** Bug 304424 has been marked as a duplicate of this bug. ***
For me this appears to be fixed in verison 4.8.5 (I upgraded from 4.8.3).
yes, this should be fixed. so I'm resolving. feel free to reopen in the future if needed.
Fixed ??? :) We never fixed it. and it's still here.
Created attachment 75138 [details] New crash information added by DrKonqi kontact (4.8.5) on KDE Platform 4.8.5 (4.8.5) using Qt 4.8.1 - What I was doing when the application crashed: I tried opening the entry completion order of the context menu in Field "To:". Then Kontact crashed. -- Backtrace (Reduced): #13 0x003a45aa in KPIM::CompletionOrderEditor::~CompletionOrderEditor (this=0xbff6c578, __in_chrg=<optimized out>) at ../../libkdepim/completionordereditor.cpp:243 #14 0x01f7cd11 in QObjectPrivate::deleteChildren (this=0xb704ae8) at kernel/qobject.cpp:1908 #15 0x0111e17c in QWidget::~QWidget (this=0xccfb690, __in_chrg=<optimized out>) at kernel/qwidget.cpp:1676 #16 0x0154f54f in QLineEdit::~QLineEdit (this=0xccfb690, __in_chrg=<optimized out>) at widgets/qlineedit.cpp:357 #17 0x007cd2ff in KLineEdit::~KLineEdit (this=0xccfb690, __in_chrg=<optimized out>) at ../../kdeui/widgets/klineedit.cpp:247
This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present? If noone confirms this bug for a Framework-based version of kdepim (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months.
The crash is still reproducible with the steps in comment 2 with kmail from KDE Applications 16.04.3. Updated backtrace Application: Kontact (kontact), signal: Segmentation fault Using host libthread_db library "/lib64/libthread_db.so.1".
