I dont have too many experience with code. I expect that this information will be helpfull to improve the code.

[wuischke]

Thank you for the extensive report.

Fortunately we have made progress since 18 February and released 2.2.2 not too long ago, where this crash, which has been reported frequently on Ubuntu systems, shouldn't happen anymore.

Please update your aMule version and see if it still happens.

[Basajaun73]

Thanks for the quick answer. I will update and test
