I was running e17 under valgrind, and encountered the following error. I'm not all that familiar with the code, but it looks like it may be a race condition in eet, between the main thread clearing the cache when idle, and another thread trying to preload images?
The first two errors (write contains uninitialised bytes) happened immediately after starting e17, and seem to be unrelated. The "invalid read" errors occured when bringing up the Gadget Settings.
