【报Bug】部分机型拍照选择的时候，出现app闪退，跳回到app主页，这是什么原因？？

示例代码：

    //上传图片  
    async chooseFile() {  
        let that = this;  
        uni.chooseImage({  
            count: that.maxCount - that.imageList.length, //图片大于1可以多选,这样可以不超出最大上传值  
            sourceType: ['camera'],  
            sizeType: ['original'],  
            success: res => {  
                uni.showLoading({  
                    title: '正在上传'  
                });  
                res.tempFilePaths.forEach(item => {  
                    that.uploadFile(item);  
                });  
            },  
            fail: err => {  
                that.$emit('uploadFail', err);  
            },  
            complete: () => {}  
        });  
    },  
    //图片数据上传后端  
    uploadFile(path) {  
        let that = this;  
        uni.uploadFile({  
            url: `${that.$config.uploadUrl}`,  
            filePath: path,  
            formData: that.formData,  
            header: {  
                'X-Access-Token': that.$store.getters.token  
            },  
            name: 'file',  
            success: res => {  
                let data = JSON.parse(res.data);  
                if (data.success) {  
                    that['value'].push(data.message);  
                    that.$emit('list', that.value); //通知父组件有图片更新  
                } else {  
                    uni.showToast({  
                        icon: 'none',  
                        title: data.message  
                    });  
                }  
            },  
            fail: err => {  
                that.$emit('uploadFail', err);  
            },  
            complete: () => {  
                uni.hideLoading();  
            }  
        });  
    },  
    //删除图片  
    delectImg(i) {  
        let that = this;  
        uni.showModal({  
            title: '提示',  
            content: '确定要删除照片吗？',  
            cancelText: '取消',  
            confirmText: '确定',  
            success: res => {  
                if (res.confirm) {  
                    that.imageList.splice(i, 1);  
                    that.$emit('input', this.imageList);  
                    that.$emit('list', that.imageList); //通知父组件删除了数据  
                }  
            }  
        });  
    },  
    //点击预览图片  
    doPreviewImage(current) {  
        let that = this;  
        uni.previewImage({  
            current,  
            urls: that.imageList, //存放图片的数组  
            loop: true,  
            indicator: 'default'  
        });  
    }
