  I dug in the history of KCrash and realized, that closing all the file descriptors was introduced (7bbf112e5e97d40b9a4f9fdd167b064a1019843b <https://phabricator.kde.org/R446:7bbf112e5e97d40b9a4f9fdd167b064a1019843b>) to make the X11 window disappear.
  Later @ossi added the X11 FD explicitly (7ac326ddb05eec296fdfbebd86d0d1320e579063 <https://phabricator.kde.org/R446:7ac326ddb05eec296fdfbebd86d0d1320e579063>), but kept closing the FDs by default.
  
  I think keeping the FDs should be the default. However, the only program I found that is explicitly setting `KCrash::CrashFlag::KeepFDs` is #falkon <https://phabricator.kde.org/tag/falkon/>, the rest seems to be fine without (except me with KDevelop).
