-- Information about the crash:
I've seen this problem a few times over the last few weeks. Kate crashes while editing Rust files (with LSP client working with Rust-Analyzer). No known steps to reproduce, possibly race condition. Possibly wayland-related.

The reporter is unsure if this crash is reproducible.

-- Backtrace:
Application: Kate (kate), signal: Segmentation fault
Content of s_kcrashErrorMessage: std::unique_ptr<char []> = {get() = 0x0}
