Dolphin crashes when more than one file is selected

Help
,
1

I have set a single click to open files and folders.

Now, when I select one file in dolphin using the selection marker, everything is as expected. However, when I select another file using the same way, dolphin crashes immediately.

When I start dolphin from konsole:

$ dolphin
ASSERT: "m_selection.count() == 1" in file /workspace/build/src/panels/information/informationpanel.cpp, line 242
KCrash: Application 'dolphin' crashing... crashRecursionCounter = 2

It seems to have started after yesterday’s kf 6.25 and kde apps 26.04 update…

Can anybody confirm, or is it something special to my system?

No issue for me. see screenshot

If I’m correct, Tumbleweed has not updated kde apps to 26.04.

This has also been happening to me since yesterday. I sent the automated crash report

Can you share the stack-trace please:

coredumpctl debug dolphin -A "-ex bt -ex quit" |& tee backtrace.txt

Ref: Debug symbols for all!

Is it ok this way?

Additional info: if files are selected using Ctrl+A or drawing a rectangle with mouse over more that one file, then no crash. It seems to be connected somehow to selection markers…

You are right. The mirror I checked (acc.umu.se) has still dolphin 25.12.3 and is probably outdated…

You are using neon, I missed that, so you have more assertion enabled.

There is a weakness here:

I needs a little investigation, the code could use some cleanup but a fix will be easy.

11

I think the crash only can occur when toggling on/off the show item on hover option of the information panel.

panels/information: when not hovering anything show selection (!1251) · Merge requests · System / Dolphin · GitLab will fix this.

12

Hi Evryone,

Same issue here, Dolphin 26.04.0 on KDE Neon

Dolphin doesnt crash when I disable the info panel.

I can’t post the result of : coredumpctl debug dolphin -A “-ex bt -ex quit” |& tee backtrace.txt

There is to many character (6000 for 3200 allowed here) an I can’t post a link.

13

Yeu can copy the end of it.
There should be a line similar to this:

#15 0x00007a2bde14dc11 in qt_assert (assertion=<optimized out>, file=<optimized out>, line=<optimized out>) at /workspace/build/src/corelib/global/qassert.cpp:113

I would expect another crashe to exhibit the same stacktrace.
