Task terminates after showing "(reasoning omitted)" when entering background execution
Description
During execution of a task that requires background processing, the TUI enters a "thinking" state, displays (reasoning omitted), and then unexpectedly terminates without completing the remaining tasks. No further output or error is shown.
Steps to reproduce
- Start DeepSeek-TUI.
- Request a task that triggers background execution (e.g., a long-running tool call or a multi-step reasoning task).
- Observe the TUI behavior.
Expected behavior
The TUI should continue processing the background task, show incremental reasoning (or a proper progress indicator), and complete all subsequent steps without crashing or terminating.
Actual behavior
After (reasoning omitted) appears, the TUI abruptly stops – the session ends, and no further interaction is possible. The remaining tasks are never executed.
Environment
- OS: Ubuntu 24.04
- DeepSeek CLI version: v0.8.28
- Model: deepseek-v4-flash
- Shell: bash
