Same issue here, but on FreeBSD.
If I try to change/edit/create new transaction in any account it just freezes with a 1.2GB core file.

If I click on Schedule and enter transaction [per schedule] there, all is good, it adds that entry and I can save without crashing.

bobbilly:  Please provide some more details - which version of KMM?  Does it crash or freeze, and does it do so on trying to add/edit a transaction, or on trying to save the file?  Can you run under strace to see where it is failing?  Does a consistency check show any problems?

kmymoney 5.0.1 - compiled from ports several days ago.
FreeBSD 11-STABLE amd64
No problems with 4.8, upgraded to 5.0.1.

Never heard of consistency check, but will try it later today.
Will try strace also.

If I go to Schedule and Enter a due bill from there, I get the Confirm window, fill that out and Enter, save kmymoney file - that is fine.

If I go to Ledger [tried at least 3 accounts], as soon as I click on 'New' or 'Edit' or double click an existing transaction it just does a hard freeze.  I sit and watch as it dumps a 1.2GB core file into my home directory, then the application window crashes/disappears.

The transactions entered via schedule are there when I start it back up and all seems good.

Terminology issue: that's a crash, not a freeze.  A freeze would just sit there forever, until you kill it.  If it dumps core, it has crashed, and I wonder if there might be a backtrace someplace.  I don't know BSD, but you could probably extract some useful information from that core dump, although I have no idea what tools you would need to do so.  

It sounds like it has something to do with the ledger.  Can you display the ledger, right click on a transaction and at least get the pop up context menu?

I can right click on a transaction, then as soon as I click 'edit' it crashes.

I'm not really sure if my patch has made anything better, so it would be helpful if you could compile yourself master branch. If it doesn't work, then please reopen this bug.

Kwanza.Pili - can you also test if this patch prevents the crash for you?

Nope - recompiled with master [has that commit in there] - as soon as I hit 'edit' on a transaction, it crashes.

Proposed change to fix problem

@bobbilly5: Can you check if this patch against master solves the problem for you?

just pulled latest master from https://github.com/KDE/kmymoney - applied your patch.  Still no go.
backtrace looks to be the same.

..hmmm - not sure if I was able to test with latest patch - failing to compile it now, so probably missed that error earlier and just ran the old version.  Will try again tomorrow.

With the master branch, I cannot even build it successfully. It fails at kfindtransactiondlg.cpp. I suspect this due to the fact that I upgraded to QT-5.11. Now I get errors such as:
kmymoney-master/kmymoney/dialogs/kfindtransactiondlg_p.h:108:130: error: no matching function for call to ‘KFindTransactionDlg::connect(QHeaderView*, void (QWidget::*)(const QPoint&), KFindTransactionDlg* const&, void (KFindTransactionDlg::*)())’

With the stable v5.0.1, the build is successful but the crash happens as before - any attempt to load/edit/modify data will crash the application. Essentially, all it succeeds in doing is starting up.

Same issue. If I go into the ledger and click on 'new' or 'edit' instant crash. 1.2GB core file

If I go and "Enter Schedule"  - that is all fine, the transaction is added to ledger.  If I then try to 'Edit' that transaction it core dumps.

My compilation issues was due to library upgrade [mesa-lib], other things also quit working - recompiled with newer library, other things are back to working and kmymoney compiles.

I think that there may be two crashes here. I see that it crashes in installEventFilter now. There are many installEventFilter and removeEventFilter and I bet calls to them are uneven.

ugh - false alarm, sorry for the noise.
Started looking at the FreeBSD port patches that get applied, usually they are things like path changes, or naming, etc.
If I compile kmymoney 5.0.1 without this patch, I can edit transactions.  With this patch applied it crashes.  Even when I compiled from -master, this patch was still bing applied by ports.

not sure why that line is commented, but I dont' apply this patch I can edit transactions and add new transactions to ledger.

opened bug with FreeBSD ports

(In reply to Kwanza.Pili from comment #14)
I do agree there are several different issues here, however I also get the same compile error, with qt 5.11 and gcc 8.0 or 8.1. (Artix linux)  I'll open a separate bug to track that down.

It seems that https://cgit.kde.org/kmymoney.git/commit/kmymoney/widgets/qwidgetcontainer.cpp?id=2f823a4603f1d9c823f3498e74f3fa05960e2383 (i.e. the patch from comment#11 ) does indeed fix the originally reported crash.

See also https://bugzilla.opensuse.org/show_bug.cgi?id=1100025 .

Yes, the fix seems to work for me. So far I've only tested adding transactions and editing payees, but not importing files yet.

Is this still a problem, or can we re-close?

(In reply to Jack from comment #23)
> Is this still a problem, or can we re-close?

As I see it, the originally reported problem was fixed by https://cgit.kde.org/kmymoney.git/commit/kmymoney/widgets/qwidgetcontainer.cpp?id=2f823a4603f1d9c823f3498e74f3fa05960e2383 (and the reporter confirmed it in comment#22), so this should be re-closed, yes IMHO.

BUT: that fix should be merged to the 5.0 branch as well I'd say (it's only in master currently), in case there will be a 5.0.2 release.

Then I'm closing this again.  There will be either a 5.0.2 or 5.1 release in the near future, and this fix is planned to be included.  There are a number of bug fixes in both branches, so one will likely be merged into the other before the release.  That bit of git magic is beyond my pay grade, but the developers are aware of it.

No problem from the openSUSE side, we do have the fix in our 5.0.1 packages meanwhile... ;-)

Agreed with closing it. Thanks.
