I was running a RKWard 0.8.2 pre-release version rkward-0.8.2~pre^1.gitc45a3696-1.fc42.x86_64 in Plasma 6.4.0 on Wayland in a Fedora 42 KDE installation. I opened a saved workspace with a data set named bp. The data contained a variable Days which was shown as type Unknown in the data set viewer. I changed the type of Days to 1: Numeric in the data set viewer. I opened an R script file which had lines that calculated Days in a way that I think created it as type Unknown or Date again. dates = as.Date(paste(bp$Month,bp$Day,bp$Year,sep="-"),tryFormats="%m-%d-%Y"); bp$Days = dates -dates[1] I ran Run all the first time I saw this problem. RKWard crashed. The first time RKWard ran drkonqi couldn't find the core dump file. A second drkonqi notification was shown, but the full trace couldn't be created. I reproduced the crash running each of the two lines one at a time. RKWard crashed in RKVariable::setNumericFromR after the second line of my program. The crash was a segmentation fault when that function was on row 0 of the data set. The pointers in data->cell_doubles were null, but they might not have been initialized yet.

/usr/src/debug/qt6-qtbase-6.9.1-1.fc42.x86_64/src/corelib/kernel/qobject.cpp:1461 When I ran bp$Days = as.numeric(dates -dates[1]) , the problem didn't happen. The problem seemed to be due to assigning a Date object to a numeric variable. I reproduced the problem in a simpler way by creating a new workspace and data set my.data which had a numeric variable var by default, then running my.data$var = as.Date("1-1-2025",tryFormats="%m-%d-%Y") in the R console. The first time I tried this, the crash had the same sort of trace, but the second time, the trace was different. KXMLGUIFactory::container had this=0x0, which might've resulted in a null pointer dereference in std::__uniq_ptr_impl<KXMLGUIFactoryPrivate, std::default_delete<KXMLGUIFactoryPrivate> >::_M_ptr. The trace referred to a context menu such as in TwinTable::contextMenu, and I did use a context menu to copy the line from a script file to the R console before changing it. I'm not sure if this is the same problem.

/usr/src/debug/rkward-0.8.2~pre^1.gitc45a3696-1.fc42.x86_64/rkward/main.cpp:294 Reproducible: Always Steps to Reproduce: 1. Start RKWard 2. create a new workspace and data set my.data which has a numeric variable var by default 3. In the R console, run my.data$var = as.Date("1-1-2025",tryFormats="%m-%d-%Y") To see the first type of trace, enter the line above without using a context menu to copy and paste it. Actual Results: RKWard crashed in RKVariable::setNumericFromR when running lines which replaced a variable set to Numeric with a Date object Expected Results: RKWard should've assigned the Date values to the numeric variable without crashing Additional Information: I reported this problem at https://bugs.kde.org/show_bug.cgi?id=505955 Application: rkward (0.8.1z+0.8.2+devel1) ApplicationNotResponding [ANR]: false Qt Version: 6.9.1 Frameworks Version: 6.15.0 Operating System: Linux 6.15.3-200.fc42.x86_64 x86_64 Windowing System: Wayland Distribution: "Fedora Linux 42 (KDE Plasma Desktop Edition)" DrKonqi: 6.4.0 [CoredumpBackend]
