kstars (2.0.0) on KDE Platform 4.7.00 (4.7.0) "release 6" using Qt 4.7.3

- What I was doing when the application crashed:
KStars crashes during start-up after upgrading to KDE 4.7.

My distribution is OpenSUSE 11.4.

it seems to be a 64bit problem.

i tried the same kstars install on an 32bit 11.04 kubuntu and it worked out of the box.

olaf - is the SUSE in question 64bit, too? then may be you try on an 32bit / same version number and have another look.

i don't know much about linux' internal programming - but the error "stringToLongLong" seems to indicate a wrong format for some variable. which may point to a 64/32bit issue...

*** Bug 279486 has been marked as a duplicate of this bug. ***

Could not reproduce with latest version from git on 32 bit system. 

AFAIU calls to QString::toInt should not result in segfaults for any string. So one possibility is that input is not checked sufficiently or there is bug in Qt (which is unlikely).

I had just finished upgrading KDE to 4.7.1 using the kde47 repository. Afterward, I noticed that kstars was no longer installed. I reinstalled it. When offered the chance to run it by Get and Remove Software KDE Control Module, I clicked the link and tried to run the program. It would not run. I tried several times with no success.

- Custom settings of the application:
KStars downloaded additional data .dat files

---

From bug 282252 comment 1:
- What I was doing when the application crashed:
Trying to launch Kstars several times. It might be related to this crash
because I do seem to recall updating data files to include more stars before
this started happening. I cannot run kstars at all. It starts up but crashes
immediately. I will try to delete the Kstars data directory and see if this
helps.
- Update:
I just deleted the kstars data files out of the kstars directory (located in
/home/<username>/.kde/apps/) and kstars now launches and runs without errors.
Something involving adding additional stars dat files causes the crashing on
startup. I do not know what it is at the moment but clearing the kstars
directory stopped the repeated crashing. So far the program is working again.
I have no attachments to add at the present but will add more data as I find
the time.

I am no longer experiencing this crash, at least not since I removed the files from the program's data directory in my home folder and uninstalled all installed KStars Add-ins. I have since upgraded KDE several times until I am now at 4.7.2. Also recently updated were Qt components.

KStars still is as version 2.0.0.

Current version of Qt now displays 4.8.0 RC1 rather than 4.8.0 beta. Exact package version is 4.8.0-0.15.rc1.fc16 and core package name is qt.x86_64. qt.i686 package is not installed.

I now am using Fedora 16-Beta x86_64. At the time of the crashes I was using Fedora 15 x86_64, followed by Fedora 16-Beta of the same architecture.

If you do that Kstars will still say the data is installed.  If you try to uninstall it from the panel and restart Kstars you will notice it still says the various packages are installed.

To remove that information you need to delete:
~/.kde4/share/apps/knewstuff3/kstars.knsregistry

I run Kstars on Gentoo, 
Qt: 4.7.4
KDE Development Platform: 4.7.2 (4.7.2)
KStars: 2.0.0

The only time I find that Kstars fails to launch from a clean install is if I try to install UNSO catalogue.

That did not happen on my system. Everything was listed as being uninstalled (all buttons have text that reads "Install" on them) after doing what I did. Of course, as I mentioned above, I manually uninstalled each entry while in the process of deleting the entire contents of the folder while leaving the data folder inside my home folder.

UNSO sounds familiar. That may be part of the cause of the crash after all. I'll have to experiment with that.

I just checked that kstar crashes at sturtup.
My setup is kubuntu 11.04 32bit.
The kstar directory and kstarrc are in this link

Finally I'm able to reproduce the crash. It look like crash really related to memory corruption.

Hi, I observed this crash also on MacOSX with kstars installed via MacPorts, but only after I had installed additional components from inside kstars.

dtrace showed that said asteroids.dat is the last file opened before DrKonqi is called:

New code expect astroids.dat and comets.dat in csv format with

Trivial to fix if spotted.

Thank you everyone for reporting. Bug is fixed now. Fix will appear in 4.7.3 and 4.8. 

While you didn't get fix yet there is simple workaround. Delete files comets.dat and asteroids.dat from ~/.kde/share/apps/kstars.

Deleted asteroids.dat and comets.dat, still crashes on start-up. What's the fix?

Sometimes you have to clear the contents of the entire application directory in your home directory (leave the application directory there so it does not have to be recreated at program launch, as that also can generate errors from time to time).

After this, the program should load. Open up the dialog you used to install the asteroids data files and check to make sure each option's button doesn't say "Installed." Any that do, click the button to uninstall that option. Close the program and launch it again. Reinstall all the data you had installed before. 

That should do it.
