Comment 5 Pino Toscano 2009-06-09 19:21:25 UTC

SVN commit 979394 by pino:

KAboutData contains a list of KAboutLicense's, and each KAboutLicense object contains a pointer to the KAboutData which created it.
The problem is that when copying a KAboutData, its licenses are copied, but the KAboutLicense objects still point to the previous KAboutData.
Thus, change the pointer in KAboutLicense (after detaching the shared data pointer) when KAboutData is copied.
Also with a small unit test case which should be a sentinel of such crashy situation.
BUG: 164092
