> Ok, I dug into this and ran a bunch of tests. I don’t know why this crash only occurs when running by double clicking the app and not by running from Terminal or QT Creator. It is very inconvenient to have an error that won’t happen when you run the code in a debugger and then will happen every time if you don’t! I had thought that maybe it was something with MacOS sandboxing or gatekeeper, or maybe it was something with packaging, or maybe it was something with environment variables. But as far as I could tell through my tests it is none of those. I printed the environments in a QMessagebox and they were slightly different, but not in any way that mattered I think. The packaging was not the culprit because it happened in the app both before and after packaging and I was running it on the same machine, so it should not be the issue. I haven’t fully ruled out something with MacOS, but I don’t currently think that is what it is since there was no error message or warning that pops up about the app being blocked from doing something it wasn’t supposed to.<br class="">

That let me rule out a lot of the commit. Then I added some Qmessagebox debug dialogs to see exactly when it would fail. As of now, it seems that the crash is entirely based on what happens when constructing the Find Dialog in find dialog.cpp. Specifically, it happens here:<br class="">
> <br class="">
> m_asyncDBManager(new CatalogsDB::AsyncDBManager(CatalogsDB::dso_db_path()))<br class="">
> <br class="">
> On line 65 when it constructs the new Asynch DB Manager. I did try changing the couple of lines of code in find dialog.cpp and find dialog.h so that it would use the old manager code from before this commit to verify if the new AsynchDBManger was really the culprit. And yes, it worked fine with the old code. So then I changed it back. Then I played around with the constructor for that class. Very strangely, I found that when I put my test QMessageBox message in just after line 772:<br class="">

> It didn’t crash when it printed my debug QMessagebox but it did crash when I didn’t have it there! That got me thinking that maybe for some reason, this object needed a little more time in its constructor for some reason, even though there are no more commands after that. So I just added a sleep command to see if that would serve the same purpose and it worked!<br class="">

I did some experiments today and I found that if I run kstars from the command line or in a debugger, the find dialog works fine, but when running the app by double clicking it crashes when you first access the find dialog. This seems to me to indicate an environment issue, like maybe an issue with environment variables or maybe a link to a library that isn’t properly in the app. I will check further.<br class="">

I made several changes to the Find Dialog in the most recent version, notably performing asynchronous database queries through another thread. It never crashed on my Linux system. Also curious if someone else can reproduce it on MacOS or if it is unique to your system.<br class="">
