Please, provide more details, since I am not the owner of a region or estate and cannot reproduce this bug here...

What list did you click into (there are four lists) ?
Is the crash happening for one list, several, all ?

Thank you.

I am also not an owner of a region or estate, but I have estate management rights for a rented region ;) .

Already opening the Region/estate floater causes:
Code:
2019-04-27T16:59:40Z WARNING: LLFloaterRegionInfo::processEstateOwnerRequest: Mismatched Estate message: estateupdateinfo
2019-04-27T16:59:40Z WARNING: LLFloaterRegionInfo::processEstateOwnerRequest: Mismatched Estate message: setaccess
2019-04-27T16:59:40Z WARNING: LLFloaterRegionInfo::processEstateOwnerRequest: Mismatched Estate message: setaccess (repeated 5 times)
but maybe not related to the segfault.

The segmentation fault happens when I click anywhere in all four lists in the access tab.

I tried to add an avatar with the add-button (in the allowed list), that worked without any issue, no crash and the avatar got listed.

The warning messages are unrelated and harmless.

I tried to (artificially) add my own avatar in the lists at floater build time, but clicking on the entry does not cause a crash here.

The stack trace you posted also lets me clueless.

Could you please try and run the viewer in debug mode (typing './cool_vl_viewer --debug' in a terminal pointing inside the viewer installation directory) ?
You will of course need to have gdb installed (but all Linux distros provide a package for it).
When the crash happens, please type "bt" in the terminal and post the stack trace you get there.

gdb complained it can't find debugging symbols, however here it is the output:

OK, I think I found what the bug comes from. If you can compile the viewer yourself (it's easy under Linux), get the sources for the current release, untar them, and in the linden/indra/newview/llfloaterregioninfo.cpp file, around line 1041, amend the code to read:
Code:
//static
void LLPanelRegionInfo::onChangeChildCtrl(LLUICtrl* ctrl, void* user_data)
{
   LLPanelRegionInfo* self = (LLPanelRegionInfo*)user_data;
   if (self && ctrl)
   {
      self->updateChild(ctrl);
   }
}
Then save the file, and from a terminal pointing to linden/indra/ type ./buildlinux.sh to compile the viewer. It should cure the crash (if it does, I will publish a fixed release tomorrow).

Thank you for your fast reply :)

I compile anyway the viewer by my own. I preferred to use your binary for reporting the bug.

I recompile and report if it will be fixed.

Fixed!

It works like it should, no crash anymore, selecting and removing works now.

Thank you :)

Thank you for your report and testing. I will publish a fixed version tomorrow (I found another bug too, that would cause OpenSIM access lists display to get messed up)...
