Details
I have been installing the latest Mozilla releases for the last year (at least) and it has happened several times where the browser fails to work correctly after the installation due to the cache problems. My latest problem was with the upgrade from Mozilla 1.1 Alpha to Mozilla 1.1 Beta. After the installation a lot of the sites I normally go to ie (www.google.com) had a bunch of broken images. If I tried to view the image the browser showed and error similar to "the gif could not be displayed because it has errors". If it has errors in the cache - it should remove it from the cache and get it from the site (but that is another issue). I was only able to correct this by clearing my cache. I was thinking that all this could be avoided if mozilla would empty the cache during/after the installation. This way the browser is starting fresh.

installer knows nothing about profiles...

When the cache changes format, we increment the cache version number which will cause old caches to be cleared on startup. However, if one of the cache clients changes the format of the data they store in the cache, the cache service has no way of deetecting this. The cache clients should consider adding a verision number for their data formats as well, so they can doom old cache entries when they fetch them. cc'ing darin & pav as http and imglib are most likely suspects for the image problem mentioned in the original description.

HTTP has not changed its cache entry format. The problem sounds a lot more like data corruption to me, which begs the question... did you ever previously run two instances of mozilla using the same profile? That is no longer permitted (since mozilla 1.0 I think), but if you happened to have an old version of Netscape 6 running along side Mozilla, you could easily corrupt your disk cache.
Sounds like the same problem as bug 146285 I did have multiple version of mozilla netscape 6+ running so that may be the problem. The issue I have here is that it looks like mozilla detected that the cache was invalid because I tried to view the image directly by entering the url for the image and mozilla displayed the message similar to "the gif could not be displayed because it has errors". If it detected that there was errors displaying the file could it not assume that the cache is corrupt and clean it? Or even it the error was changed to say something like "the gif could not be displayed because it has errors - this problem may be due to your cache being currupt would you like to clear your cache". I prefere the first option. Besides what I'm I going to do with a currupt cache? I will most likely clear it to fix the problem.

The correct solution is that NS should use a different Profile. Mozilla use it's own profile Apllication Data/Mozilla and NS should use application Data/Netscape. But that is an already filed bug and it's invalid in bugzilla. see also the release notes that you should no share a profile between NS and Mozilla.
I agree this sounds like a dup of bug 146285. We will be looking at ways to more gracefully recover from problems like this. Thanks for reporting it. *** This bug has been marked as a duplicate of 146285 ***
