Random SIGABRT when setting detents

[Quader]

Hi,
when setting detents to the SnappySlider i randomly get SIGABRT.

Apparently there's is no crash Log provided though.

I ran into this Issue when i first imported it into my project.
After this i calculated the detents in another method and returned it.
This seemed solving this issue. But now its back at a random point (i did not touched the snappyslider again).

Here´s my method for setting the detents:

-(void)setDetentsForSlider:(int)numberOfPages
{
    float step = 10.0f;

    NSMutableArray * sliderDetents = [[[NSMutableArray alloc] init] retain];

    for (int i = 0; i < numberOfPages; i++)
    {
        float detent = i * step;
        [sliderDetents addObject:[NSNumber numberWithFloat:detent]];
    }

    NSArray * sliderDetentsArray = [NSArray arrayWithArray:sliderDetents];

    pageSlider.detents = sliderDetentsArray;
    [sliderDetents release];
}

Cheers Steven
