Side note: For all messages I see this error message in the logs: js: Uncaught ReferenceError: qt is not defined js: Uncaught ReferenceError: qt is not defined js: Uncaught ReferenceError: qt is not defined but it does not seem to interrupt kmail. Sorry for being incoherent: I am using qt 5.7.0, plasma 5.8.3, kde apps 16.08.2, and frameworks 5.27. The compiler is gcc 6.2.0. Looking at the stack trace again, I just remembered that v8 has problems with gcc 6 due to programming practices. I am recompiling qtwebengine with appropriate compiler flags to check if this is the underlying problem here... In a side-note, the secondary crash happens when grabbing selected text:

Update: I recompiled with "-fno-delete-null-pointer-checks -fno-lifetime-dse -fno-schedule-insns2", but the crash still happens. Then I took a look at kdepim git and found at, that there is a KF5WebEngineViewerConfig in the works. So it looks like everything will change in git, right? (In reply to Jan-Matthias Braun from comment #5) > Update: I recompiled with "-fno-delete-null-pointer-checks -fno-lifetime-dse > -fno-schedule-insns2", but the crash still happens. Yeah, looks like I did not rccompile with these CFLAGS. Now I did and it looks quite a lot better. qtwebengine is still using wrong CFLAGS for gcc 6. :-( |
