Description of problem:
Updating to version 63.2-1.fc30 cause a crash in kontact (and other qt5-qtwebengine based applications).

The crash is due to the code triggering an assert:

Comment 1 Kevin Kofler 2019-05-12 12:51:43 UTC
Looks like this also makes Falkon unusable in Rawhide, I get this on the latest Rawhide KDE Live image:
malloc(): invalid size (unsorted)
and it crashes.

I am nominating this bug as a blocker for Fedora 31 on the ground that it breaks at least one (in fact, at least 2: Falkon and Kontact) default applications on the KDE Spin, as per (lacking official criteria for Fedora 31 at this time).

It is arguable whether Falkon should actually be considered the default browser on the KDE Spin, which would make this a blocker even for the Rawhide composes as per .

Comment 2 Rex Dieter 2019-05-12 14:02:33 UTC
Interestingly, icu-63.2-1 on f29 does not appear to suffer from similar problems.  After updating to libicu-63.2-1.fc29, qtwebengine applications continue to start and run fine.

Comment 3 Rex Dieter 2019-05-12 14:13:54 UTC
My comment was erroneous, f29 updates-testing has 62.2, not 63.2, so that's probably relevant why/how f29 is unaffected

Comment 4 Eike Rathke 2019-05-13 09:50:30 UTC
Same happened for the update on F30

I'll roll back to 63.1 on rawhide.

Comment 5 Eike Rathke 2019-05-13 12:26:24 UTC
Changing Version field from f30 to rawhide because that's the important thing, the update is not included in F30 as bodhi holds it back.

Comment 6 Eike Rathke 2019-05-13 15:22:03 UTC
icu-63.2-2.fc31 should fix this, if someone could verify?

Comment 7 Fedora Update System 2019-05-13 16:07:50 UTC
icu-63.2-2.fc30 has been submitted as an update to Fedora 30.

Comment 8 Colin J Thomson 2019-05-13 18:00:16 UTC
icu-63.2-2.fc30  fixes the crashes on this F30 box, with applications that use qt5-qtwebengine.
IE Kmail, Falkon, Akregator etc

Comment 9 Fedora Update System 2019-05-14 01:54:01 UTC
icu-63.2-2.fc30 has been pushed to the Fedora 30 testing repository. If problems still persist, please make note of it in this bug report.
