Ktoon needs specific version of Qt to run

Ktoon crashes on startup, with the following backtrace:

If we can't get this app to run properly, we'll have to remove the package before the 2.0 release.

I think Synfig is going to be the more useful application in the long run, being gtk based as it is. I expect we'll have to wait for a more stable version of that to appear in lenny/sid. Probably not the most helpful comment I could have made. ;)

[daniel@…]

Unfortunately synfig is not likely to be stable in time for the 64 Studio 2.0 release, and ktoon isn't looking very hopeful either. I'll try contacting the Ktoon team again.

I've tried to built ktoon 0.8 on etch, and it fails on amd64. I've kind of workaround the problem, and I could get it built, but the app still crashes on start up.

[daniel@…]

The problem seems to be that Ktoon 0.8 relies on an obsolete version of Qt, version 4.1.4. The Ktoon developers are planning to release 0.9 built against Qt 4.2.x, but in the meantime it appears that building a static-linked binary is the only workaround.
